Ferrellgas Partners and the operating partnership, collectively referred to as “Ferrellgas,” are both Delaware limited partnerships and are governed by their respective partnership agreements. Ferrellgas Partners was formed to acquire and hold a limited partner interest in the operating partnership. As of October 31, 2014, Ferrell Companies, Inc. ("Ferrell Companies") beneficially owns 22.8 million Ferrellgas Partners common units. Ferrellgas, Inc. (the "general partner"), a wholly-owned subsidiary of Ferrell Companies, has retained a 1% general partner interest in Ferrellgas Partners and also holds an approximate 1% general partner interest in the operating partnership, representing an effective 2% general partner interest in Ferrellgas on a combined basis. As general partner, it performs all management functions required by Ferrellgas. Creditors of the operating partnership have no recourse with regards to Ferrellgas Partners.
	Ferrellgas Partners is a holding entity that conducts no operations and has two subsidiaries, Ferrellgas Partners Finance Corp. and the operating partnership.

The operating partnership is the only operating subsidiary of Ferrellgas Partners.
	Ferrellgas is engaged in the following reportable business segment activities:
	•	Propane and related equipment sales consists of the distribution of propane and related equipment and supplies.

	•	Midstream operations consists of eight salt water disposal wells in the Eagle Ford shale region of south Texas. Salt water disposal wells are a critical component of the oil and natural gas well drilling industry. Oil and natural gas wells generate significant volumes of salt water that is transported by truck to our disposal wells.

						B.	Probability of forecast	10% - 75%	N/A
	The valuation of the contingent consideration is based on unobservable inputs such as Ferrellgas' weighted average cost of capital and the likelihood of the acquired company meeting earnings thresholds. As of October 31, 2014, fluctuations in these inputs could have the following effect (in thousands):
		Increase/(decrease)
		5% increase in WACC			5% decrease in WACC			10% increase in best earnings forecast probability			10% decrease in best earnings forecast probability
	Change in the fair value of contingent consideration	$	(350	)	$	360		$	1,060		$	(1,090	)
	Methodolgy
	The fair values of Ferrellgas’ non-exchange traded commodity derivative contracts are based upon indicative price quotations available through brokers, industry price publications or recent market transactions and related market indicators. The fair values of interest rate swap contracts are based upon third-party quotes or indicative values based on recent market transactions.
	The fair value of Ferrellgas' contingent consideration for the acquisition of Sable Environmental, LLC and Sable SWD 2, LLC (collectively, "Sable") is based upon our estimate of the likelihood that the target EBITDA metric will be met and exceeded and the amount by which it could be exceeded then discounting that value at a risk- and inflation-adjusted rate. The inputs to this model are the likelihood of meeting and exceeding the target EBITDA metric and discount rate. Management and the sellers prepared an operating forecast based on Sable's operating capacities, historical performance, and projected oil and water volumes and set a target EBITDA metric. Management then assessed the likelihood of this target EBITDA metric being achieved and exceeded and assigned probabilities to various potential outcomes. To determine the appropriate discount rate, management used observable inputs such as inflation rates, short and long-term yields for U.S. government securities and our nonperformance risk. Due to the significant unobservable inputs required in this measurement, management determined that the fair value measurement of the contingent consideration liability is level 3 in the fair value hierarchy.
	Other financial instruments
	The carrying amounts of other financial instruments included in current assets and current liabilities (except for current maturities of long-term debt) approximate their fair values because of their short-term nature. At October 31, 2014 and July 31, 2014, the estimated fair value of Ferrellgas’ long-term debt instruments was $1,462.0 million and $1,408.2 million, respectively. Ferrellgas estimates the fair value of long-term debt based on quoted market prices. The fair value of our consolidated debt obligations is a Level 2 valuation based on the observable inputs used for similar liabilities.
	Ferrellgas has other financial instruments such as trade accounts receivable which could expose it to concentrations of credit risk. The credit risk from trade accounts receivable is limited because of a large customer base which extends across many different U.S. markets.

	Change in value of risk management interest rate derivatives	(1,139		)		(1,013		)
	Ending balance	$	(8,542	)		$	11,741
	Ferrellgas expects to reclassify net losses of approximately $5.2 million to earnings during the next 12 months. These net losses are expected to be offset by increased margins on propane sales commitments Ferrellgas has with its customers that qualify for the normal purchase normal sales exception.
	During the three months ended October 31, 2014 and 2013, Ferrellgas had no reclassifications to earnings resulting from the discontinuance of any cash flow hedges arising from the probability of the original forecasted transactions not occurring within the originally specified period of time defined within the hedging relationship.
	As of October 31, 2014, Ferrellgas had financial derivative contracts covering 2.5 million barrels of propane that were entered into as cash flow hedges of forward and forecasted purchases of propane.
	Derivative financial instruments credit risk
	Ferrellgas is exposed to credit loss in the event of nonperformance by counterparties to derivative financial and commodity instruments. Ferrellgas’ counterparties principally consist of major energy companies and major U.S. financial institutions. Ferrellgas maintains credit policies with regard to its counterparties that it believes reduces its overall credit risk. These policies include evaluating and monitoring its counterparties’ financial condition, including their credit ratings, and entering into agreements with counterparties that govern credit limits. Certain of these agreements call for the posting of collateral by the counterparty or by Ferrellgas in the forms of letters of credit, parental guarantees or cash. Although Ferrellgas has concentrations of credit risk associated with derivative financial instruments held by certain derivative financial instrument counterparties, the maximum amount of loss due to credit risk that, based upon the gross fair values of the derivative financial instruments, Ferrellgas would incur if these counterparties that make up the concentration failed to perform according to the terms of their contracts was $0.8 million at October 31, 2014.
	Ferrellgas holds certain derivative contracts that have credit-risk-related contingent features which dictate credit limits based upon the operating partnership’s debt rating. At October 31, 2014, a downgrade in the operating partnership’s debt rating would not trigger any further reduction in credit limit. There were no derivatives with credit-risk-related contingent features in a liability position on October 31, 2014 and Ferrellgas had no collateral posted in the normal course of business related to such derivatives.

	Ferrellgas’ operations are subject to all operating hazards and risks normally incidental to handling, storing, transporting and otherwise providing for use by consumers of combustible liquids such as propane. As a result, at any given time, Ferrellgas can be threatened with or named as a defendant in various lawsuits arising in the ordinary course of business. Other than as discussed below, Ferrellgas is not a party to any legal proceedings other than various claims and lawsuits arising in the ordinary course of business. It is not possible to determine the ultimate disposition of these matters; however, management is of the opinion that there are no known claims or contingent claims that are reasonably expected to have a material adverse effect on the consolidated financial condition, results of operations and cash flows of Ferrellgas.
	The Federal Trade Commission (“FTC”) initiated an investigation into certain practices related to the filling of portable propane cylinders. On March 27, 2014, the FTC filed an administrative complaint alleging that Ferrellgas and one of its competitors colluded in 2008 to persuade a customer to accept the cylinder fill reduction from 17 pounds to 15 pounds.  The complaint does not seek monetary remedies.  Ferrellgas reached a settlement with the FTC during the three months ended October 31, 2014 without any financial payment; the settlement has been approved by a vote of the Commission and is in a public comment period.
	Ferrellgas has also been named as a defendant, along with a competitor, in putative class action lawsuits filed in multiple jurisdictions. The complaints, filed on behalf of direct and indirect customers of our tank exchange business, reference the FTC complaint mentioned above.  The lawsuits allege that Ferrellgas and a competitor coordinated in 2008 to reduce the fill level in barbeque cylinders and combined to persuade a common customer to accept that fill reduction, resulting in increased cylinder costs to retailers and end-user customers in violation of federal and certain state antitrust laws.  The lawsuits seek treble damages, attorneys’ fees, injunctive relief and costs on behalf of the putative class.  The lawsuits have been consolidated by a multidistrict litigation panel.  We believe we have strong defenses to the claims and intend to vigorously defend against the consolidated case.  Ferrellgas does not believe loss is probable or reasonably estimable at this time related to the putative class action lawsuit.
	Ferrellgas has also been named as a defendant in a putative class action lawsuit filed in the United States District Court in Kansas. The complaint was the subject of a motion to dismiss which was granted, in part, in August 2011. The surviving claims allege breach of contract and breach of the implied duty of good faith and fair dealing, both of which allegedly arise from the existence of an oral contract for continuous propane service. Ferrellgas believes the claims are without merit and intends to defend them vigorously. The case has not been certified for class treatment. Ferrellgas recently prevailed on an appeal before the Tenth Circuit Court of Appeals and the appellate court ordered the trial court to determine whether the case must be arbitrated. Ferrellgas does not believe loss is probable or reasonably estimable at this time related to this putative class action lawsuit.

Earnings Per Share [Abstract]	'
Net Earning Per Common Unitholders' Interest	'
	Net loss per common unitholders’ interest
	Below is a calculation of the basic and diluted net loss per common unitholders’ interest in the condensed consolidated statements of earnings for the periods indicated. In accordance with guidance issued by the FASB regarding participating securities and the two-class method, Ferrellgas calculates net earnings (loss) per common unitholders’ interest for each period presented according to distributions declared and participation rights in undistributed earnings, as if all of the earnings or loss for the period had been distributed. Due to the seasonality of the propane business, the dilutive effect of the two-class method typically impacts only the three months ending January 31. In periods with undistributed earnings above certain levels, the calculation according to the two-class method results in an increased allocation of undistributed earnings to the general partner and a dilution of the earnings to the limited partners as follows:
		Ratio of total distributions payable to:
	Quarterly distribution per common unit	Common unitholder			General partner
	$0.56 to $0.63	86.9	%		13.1	%
	$0.64 to $0.82	76.8	%		23.2	%
	$0.83 and above	51.5	%		48.5	%
	There was no dilutive effect resulting from this guidance on basic and diluted net earnings per common unitholders' interest for the three months ended October 31, 2014 and 2013.
	In periods with net losses, the allocation of the net losses to the limited partners and the general partner will be determined based on the same allocation basis specified in Ferrellgas Partners’ partnership agreement that would apply to periods in which there were no undistributed earnings. Additionally, there are no dilutive securities in periods with net losses.

Segment Reporting Disclosure [Text Block]	'
	Segment reporting
	During May 2014, Ferrellgas entered into a membership interest purchase agreement to acquire all of the issued and outstanding membership interests of Sable, a fluid logistics provider in the Eagle Ford shale region of south Texas. With this acquisition Ferrellgas established a new operating and reportable segment referred to as “Midstream Operations” in addition to the existing reportable segment of propane and related equipment sales. The chief operating decision maker evaluates the operating segments using an Adjusted EBITDA performance measure which is based on net loss before income tax benefit, interest expense, depreciation and amortization expense, non-cash employee stock ownership plan compensation charge, non-cash stock-based compensation charge, loss on disposal of assets, other income (expense), net, change in fair value of contingent consideration and litigation accrual and related legal fees associated with a class action lawsuit. This performance measure is not a GAAP measure but the components are computed using amounts that are determined in accordance with GAAP. A reconciliation of this performance measure to net loss attributable to Ferrellgas Partners L.P., which is its nearest comparable GAAP measure, is included in the tables below. In management's evaluation of performance, certain costs, such as compensation for administrative staff and executive management, are not allocated by segment and, accordingly, the following reportable segment results do not include such unallocated costs. The accounting policies of the operating segments are otherwise the same as those described in the summary of significant accounting policies in Note B.
	Assets reported within a segment are those assets that can be identified to a segment and primarily consist of trade receivables, property, plant and equipment, inventories, identifiable intangible assets and goodwill. Cash, certain prepaid assets and other assets are not allocated to segments. Although Ferrellgas can and does identify long-lived assets such as property, plant and equipment and identifiable intangible assets to reportable segments, Ferrellgas does not allocate the related depreciation and amortization to the segment as management evaluates segment performance exclusive of these non-cash charges.
	The propane and related equipment sales segment primarily includes the distribution and sale of propane and related equipment and supplies with concentrations in the Midwest, Southeast, Southwest and Northwest regions of the United States. Sales from propane distribution are generated principally from transporting propane purchased from third parties to propane distribution locations and then to tanks on customers’ premises or to portable propane tanks delivered to nationwide and local retailers. Sales from portable tank exchanges, nationally branded under the name Blue Rhino, are generated through a network of independent and partnership-owned distribution outlets.
	Salt water disposal wells are a critical component of the oil and natural gas well drilling industry. Oil and gas wells generate significant volumes of salt water known as “flowback” and “production” water. Flowback is a water based solution that flows back to the surface during and after the completion of the hydraulic fracturing (“fracking”) process whereby large volumes of water, sand and chemicals are injected under high pressures into rock formations to stimulate production. Flowback contains clays, chemicals, dissolved metal ions, total dissolved solids and oil/condensate. Production water is salt water from underground formations that are brought to the surface during the normal course of oil or gas production. Because this water has been in contact with hydrocarbon-bearing formations, it contains some of the chemical characteristics of the formations and the hydrocarbons. In the oil and gas fields we service, these volumes of water are transported by truck away from the fields to salt water disposal wells where it is injected into underground geologic formations using high-pressure pumps. Revenue is derived from fees charged to customers to dispose of salt water at the disposal facilities and crude oil sales from the skimming oil process.
	Prior to the Sable acquisition in May 2014, Ferrellgas managed and evaluated its operations as a single reportable segment. As the current two reportable segment structure is the result of the Sable acquisition completed during May 2014, comparative historical segment information for fiscal 2014 is not provided.
