Optimizing nutrient management for farm systems.
Increasing the inputs of nutrients has played a major role in increasing the supply of food to a continually growing world population. However, focusing attention on the most important nutrients, such as nitrogen (N), has in some cases led to nutrient imbalances, some excess applications especially of N, inefficient use and large losses to the environment with impacts on air and water quality, ...

متن کاملNutrient removal from farm effluents.
The objectives of the study were: (i) to examine the efficiency of nutrient removal during the treatment of dairy farm effluent in a two-pond system, and (ii) to produce an inexpensive but effective nutrient trap which could be recycled as a nutrient source or soil mulch. The concentration of chemical oxygen demand (COD), biological oxygen demand (BOD), nitrogen (N), phosphorus (P) and potassiu...
متن کاملDevelopment ofbioconsortia for optimizing nutrient supplementation through microbes for sustainable tobacco production
Increased interests in low-input agriculture in recent years has seen the growing developmentin the use of commercial biological inoculants to increase the mobilization of key nutrients suchas nitrogen (N), phosphorus (P) and potassium (K) to enhance their availability to crop plants.The objectives of this field experiment with tobacco were to determine i) reduced rates ofinorganic fertilizer c...
