Mining of nutrients from soil is a major problem causing soil degradation and threatening long-term food production in developing countries. In present research, an attempt was made for carrying out nutrient budgeting, which includes the calculation of nutrient balance at micro (plot / field) and meso (farm) level and evaluation of trends in nutrient mining / enrichment. A nutrient budget is an...

Zeolites have been increasingly used in various application areas such as industry, agriculture, environmental protection, and even medicine. Although, there are no certain figures on the total amount of these minerals the world, some countries e.g. Cuba, USA, Russia, Japan, Italy, South Africa, Hungary and Bulgaria, have important reserves and production potentials. According to reports of 200...

Potato is a vital food source for the high hills of Nepal. The crop requires right amount nutrient at appropriate time optimal growth and production. However, low availability, cost, inappropriate timing applying nitrogenous fertilizers like urea have made it challenging farmers to use correct in their fields. Therefore, affordable renewable sources plant nutrients should be used supplement che...

The field experiment was conducted to evaluate the different sources of organic manures in comparison with recommended dose fertilizer (RDF) on greengram at South farm, Karunya Institute Technology and Science, Coimbatore, India. laid out Randomized Block Design replicated thrice during kharif rabi seasons 2022. study comprised nine treatments, two treatments sole 100% N equivalent basis (vermi...

Brassica plants once incorporated into soil as green manures have recently been shown to have biofumigant properties and have the potential of controlling plant-parasitic nematodes. In Washington State, plant-parasitic nematodes are successfully managed with synthetic nematicides. However, some of the synthetic nematicides became unavailable recently or their supply is limited leaving growers w...

Effect of composting on the extractability of plant nutrients in organic wastes is essential for their recycling in sustainable soil fertility management. Therefore, an experiment was carried out to determine the concentrations of total C, total N, extractable P, K, Na and B in five types of fresh and composted manures (namely buffalo, camel, cow, goat and poultry). Laboratory results showed th...
