Nutrient losses due to leaching, volatilization and fixation and the activated risk of nitrate leaching after fertilizer addition to the soil may be reduced through the use of slow-release fertilizers. Turmeric, a long duration and high yielding commercial crop consumes greater amount of nutrients from the soil as well as from applied fertilizers for a prolonged period. A field experiment was c...

Abstract Fertilization in the seedling production phase is essential to form quality seedlings. Thus, aim of this study was evaluate appropriate doses two slow-release fertilizers (SRF1 and SRF2) their nutrient leaching behavior. For this, five different were tested. 0, 2, 4, 6, 8 kg m-³. The height, stem diameter, leaf area, shoot dry mass, root system total Dickson Quality Index measured, for...

urea is the most common form of nitrogen fertilizer used in sugar beet cultivation. urea has a high solubility and its losses are high and consequently its efficiency is low. it is supposed that urea solubility can be limited and its efficiency can be increased by using slow-release nitrogen fertilizers. by conducting an experiment in three important sugar beet cultivation areas of khorasan pro...
