Phosphorus deficiency is a major constraint to crop production due to rapid binding of the applied phosphorus into fixed forms not available to the plants. This work was carried out to explain the release of soluble phosphates and its effect on plant growth as a function of phosphate solubilization by fluorescent Pseudomonas. In the current study, Pseudomonas fluorescens K 34 solubilized trical...

Nanotechnology fertilizers are associated with objects measuring 1 nm to 100 capable of controlling or manipulating at an atomic scale. Phosphorus is one the essential nutrients needed by plants in large amounts. Maize a strategic commodity requiring optimal nutrients. Inceptisol soil that has relatively low fertility and chemical properties. The addition P plays important role improving qualit...

Upland rice is typically grown under slash-and-burn systems in the mountainous regions of northern Laos by resource-poor farmers for subsistence. Upland rice cultivars are all traditional and no fertilizer inputs are used. In these systems, grain yields average only 1.7 t/ha. A multi-site experiment was conducted in Luang Prabang province to examine cultivar and fertilizer effects on grain yiel...

Various strategic efforts to increase food production continue be made in an effort achieve self-sufficiency and security. Soybean is a national commodity support government programs with the aim of achieving self-sufficiency. The purpose this study was determine effect combination phosphate fertilizer rhizobium biofertilizer on growth soybean (Glycine max L) Grobogan variety. research conducte...

Agricultural phosphorus (P) use is intricately linked to food security and water quality. Globalization of agricultural systems and changing diets clearly alter these relationships, yet their specific influence on non-renewable P reserves is less certain. We assessed P fertilizer used for production of food crops, livestock and biofuels in the US agricultural system, explicitly comparing the do...

Potato is an important crop in the Northwest China, however, its production constrained by water scarcity. Plastic mulching film efficient technical measure to alleviate potato restrictions. Therefore, studying response of yield and use efficiency plastic great significance. The study conducted a meta-analysis quantify effect on Northwest. then quantified effects different levels natural condit...

Process of struvite (MgNH4PO4·6H2O) precipitation is a promising method for phosphorus recycling. The use of cheap magnesium ore for precipitation struvite as phosphate recovery has been examined. The optimal conditions for precipitation are pH 9.0 and Mg: 4 NH  : 4 PO  molar ratio 1.1:30.7:1. Linear correlation of experimental data is in qualitative agreement with modelling calculation. Surf...

effects of organic manure (poultry manure) applied alone and integrated with inorganic fertilizer (urea) on yield and yield component, n-uptake and soil fertility in wheat-maize cropping system was evaluated in a field experiment at nuclear institute for food and agriculture, peshawar, pakistan. poultry manure was applied alone and were integrated in different proportions with mineral nitrogeno...

presence of arsenic, a heavy metal, in soil and water resources originating from geological formations of qorveh plain, which is considered as the main agricultural zone of kurdistan province in western iran, has put the agricultural products of this region at risk of pollution. since arsenate, as the most abundance form of arsenic in soil environment, competes against phosphate anion; applicat...

Abstract The immobilization effect of soil amendments on leaching and bioavailability Pb, Zn Cd in highly contaminated soils under industrial impact was studied by collecting the surroundings Zn-Pb Smelter “Miasteczko Śląskie” southern Poland as an example. Various amounts four additives (phosphate fertilizer, limestone powder, bentonite rock bog iron ore) were tested laboratory experiments to ...
