Phosphorus Fertilization of Sunfish Ponds
Transactions of the American Fisheries Society, 1977Abstract Phosphorus fertilization rates were reduced from 9 to 4.5 kg/hectare/application of P2O5 in ponds on a wooded watershed without significant decline in sunfish production. Evaluation of the present and an earlier study suggests that 9 kg/hectare/application of P2O5 be used for woodland ponds with heavy fishing pressure, while 4.5 kg/hectare ...

Phosphorus fertilization enhances terrestrial carbon cycling in phosphorus-deficient ecosystems
Journal of Environmental ManagementAnthropogenic phosphorus (P) input into terrestrial soils have been greatly increased, with potential effects on both above- and belowground carbon (C) cycling processes. However, uncertainty about how plant-soil-microbe systems respond to P fertilization makes it difficult to predict the effects of anthropogenic P input on the terrestrial C cycling ...

Grow More Biomass: Phosphorus Fertilizer
2021Phosphorus is one of the three elements most essential to plants. Minable phosphorus is a relatively rare commodity. What are the alternative sources? This chapter also takes a look at how phosphorus runoff can harm ecosystems.

Phosphorus Fertilization with Drip Irrigation
Soil Science Society of America Journal, 1976Abstract Application of plant nutrients with drip irrigation systems is desirable for labor and energy savings and flexibility in timing nutrient applications. Evaluations of P movement in the soil and uptake by tomatoes ( Lycopersicum esculentum ) were made when ...

Foliar nitrogen and phosphorus fertilization
This review presents a synthesis of the current state of knowledge of physiological processes, weather conditions and management factors affecting the responses of different crops to foliar fertilization with nitrogen and phosphorus. It is concluded that if foliar fertilization is carried out in the correct way under carefully optimized conditions, it ...de Castro, Saulo Augusto Quassi +1 more

Maintenance of Phosphorus Fertilizer and Residual Phosphorus Effect on Corn Production
Nutrient Cycling in Agroecosystems, 2005Phosphorus (P) deficiency is invariably a common crop growth and yield-limiting factor in unfertilized soils, especially soils high in calcium carbonate, which reduces P solubility. Even when such soils are fertilized, adsorption and desorption lead towards a reversion to stable and less soluble P forms, thus reducing fertilizer use efficiency.

Phosphorus Fertilization Impacts on Corn Yield and Soil Fertility
Communications in Soil Science and Plant Analysis, 2018ABSTRACTOptimization of phosphorus (P) fertilization is important for balancing soil fertility especially in vertisol to support economic crop production. The objective of the study was to determine the impact of P fertilization (1998 to 2014) on crop yield and nutrient uptake, and soil fertility under continuous annually tilled corn (Zea mays L ...

Phosphorus Fertilization through Drip Irrigation
Journal of Production Agriculture, 1989Although P fertilization through drip irrigation systems has not been widely recommended, a review of currently available literature indicates this fertilizer application technique can offer many advantages when performed properly. Using drip irrigation to apply P fertilizer allows nutrient placement directly into the plant root zone during critical ...

Fertilization with Phosphorus, Potassium, and Other Nutrients
2016Phosphorus and potassium are important nutrients whose management has some common characteristics since both are non-mobile nutrients in the soil. Most of P and K in the soil is not available to plants. Reactions involved in their cycle in the soil imply that only part of applied nutrients remain available for plants (retrogradation).

Dairy cows grazing a tropical grass pasture fertilized with 300 kg N/ha and with a 7-year history of phosphorus fertilizer at either 0 or 45 kg P/ha were given a P supplement in a 2 × 2 factorial experiment at Kairi Research Station, Queensland, Australia.
