Nutrient dynamics from broiler litter applied to no-till cotton in an upland soil
Applying broiler litter to the soil surface of a no-till field of cotton (Gossypium hirsutum L.) increases the potential loss of its nutrients via runoff and volatilization. An experiment was conducted over 3 yr on an upland Atwood silt loam soil (fine-silty, mixed, semiactive, thermic Typic Paleudalfs) near Pontotoc, MS, to determine the effect of broiler litter incorporation into the surface ...

Phosphorus runoff from turfgrass as affected by phosphorus fertilization and clipping management
Received for publication December 8, 2008. Phosphorus enrichment of surface water is a concern in many urban watersheds. A 3-yr study on a silt loam soil with 5% slope and high soil test P (27 mg kg–1 Bray P1) was conducted to evaluate P fertilization and clipping management effects on P runoff from turfgrass (Poa pratensis L.) under frozen and nonfrozen conditions. Four fertilizer treatments ...

Pond fertilization / Aquaculture
Just as fish need good water quality conditions to thrive, they also need an abundant supply of food to grow. We can provide food for our fish in two different ways: We can give them “artificial” feeds that are prepared either commercially or at home, or we can ensure that they have an abundance of natural foods by using fertilizers to increase pond productivity. In either case, it is ...

Potential phosphorus, potassium, and magnesium surpluses in an irrigated maize monoculture fertilized with pig slurry
Pig slurry (PS) is extensively applied to irrigated maize in nitrate-vulnerable zones of the Ebro Valley, Northeast Spain. Farmers base PS rates on the European Union (EU) Nitrates Directive (up to 170 kg N ha–1 derived from organic sources) or on maize-N requirements (about 300 kg N ha–1). The aim of the study was to assess whether these PS rates would lead to P, K, and Mg surpluses in excess of ...

Main advantages and disadvantages of granulation process and technology of potash fertilizer
The potassium fertilizer is fed into the disc granulator, so that the material gradually piles up by itself until it reaches the required particle size. When the raw materials are piled up on the disc, the binder can be added to support the agglomeration of the materials. Since water will be added to the disc during granulation, additional drying process is required for the fertilizer production ...
