Runoff phosphorus loss immediately after poultry manure application as influenced by the application rate and tillage.
Excessive or N-based application of poultry manure for crops may result in significant risk of P loss with surface runoff. This study assessed P loss immediately after poultry manure application to soybean [Glycine max (L.) Merr.] residue with and without tillage at eight Iowa fields. Manure from chickens (Gallus gallus domesticus) or turkeys (Melleagris gollopavo) was applied at intended rates...
متن کاملN uptake and yield of wheat as influenced by integrated use of organic and mineral nitrogen
The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...
متن کاملEffectiveness of Constructed Wetlands in Reducing Nitrogen and Phosphorus Export from Agricultural Tile Drainage
nutrient in estuaries. Phosphorus enters surface waters in both dissolved and particulate form and is generally Much of the nonpoint N and P entering surface waters of the the limiting nutrient in lakes. A large portion of the N Midwest is from agriculture. We determined if constructed wedands could be used to reduce nonpoint N and P exports from agricultural and P now entering U.S. freshwater ...
متن کاملSeed Yield of Groundnut (Arachis Hypogaea L.) as Influenced by Phosphorus and Manure Application at Babile, Eastern Ethiopia
Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manur...
