Polymer-coated controlled-release fertilizers (PCFs) are the most widely used fertilizers in the production of container-grown nursery plants. The duration and magnitude of PCF nutrient release varies with product and this variation can significantly affect plant growth. Three experiments were conducted to determine the long-term nutrient release patterns of three PCFs (each with a rated longev...

A large part of the Indo-Gangetic plain has marginal soils, which are depleted of nutrients and sandy with low water-holding capacity. Fertilizers and irrigation are applied to obtain regular yield. However, high usage of fertilizers and inappropriate methods of irrigation lead to a degradation of soil microfl ora and loss of soil fertility in the long term. In close collaboration with other pa...

This study was carried out in order to evaluate the changes of Nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of Leonardite and foliar application of N and K. The experiment was conducted in Gorgan University of Agricultural Sciences and Natural Resources during 2013- 2014. The experiment was laid out a using split-plot arrangement based ...

Nanotechnology is an interdisciplinary research field. In recent past efforts have been made to improve agricultural yield through exhaustive research in nanotechnology. The green revolution resulted in blind usage of pesticides and chemical fertilizers which caused loss of soil biodiversity and developed resistance against pathogens and pests as well. Nanoparticle-mediated material delivery to...

Animal manures are a valuable resource, providing readily available plant nutrients ; however, runoff from lands receiving animal manure has been shown to contribute to water pollution. Understanding the loss of nutrients from slow release fertilizers, such as animal manure, after application is critical in determining and designing practices to reduce and/or control the temporal availability a...

Fertilization is an increasingly common practice in horticulture. Nevertheless, the conventionally used fertilization method ineffective, and it generates contamination problems due to excess nutrients. Therefore, new technologies, such as nanofertilization or controlled-release systems of fertilizers, are currently being tested. Thus, main objective this work was develop for micronutrients, us...

Both organic and conventional farming processes require energy input in the form of diesel fuel for farming equipment, animal feed, and fertilizer compounds. The most significant difference between the two methods is the use in conventional farming of mineral fertilizers and pesticides that are minimally employed in organic management. It is argued that organic farming is more environmentally f...

Recently, the application of excreta-based fertilizers has attracted attention due to the strongly increasing prices of chemically produced fertilizers. Faecal sludge from on-site sanitation systems is rich in nutrients and organic matter, constituents which contribute to replenishing the humus layer and soil nutrient reservoir and to improving soil structure and water-holding capacity. Hence, ...
