Nanotechnology fertilizers are fertilizers associated with objects measuring 1 nm to 100 nm capable of controlling or manipulating at an atomic scale. Phosphorus is one of the essential nutrients needed by plants in large amounts. Maize is a strategic com... see more

This paper was assessed the mineral elements level (Co, Pb, Cr, Fe, Ni, Cu, Zn, Cd and Mn) in raw phosphate rock (PRock) that obtained from State Company For Phosphate in Anbar province. This work was achieved to add new data of microelements toward this ... see more

The aim of this study was to determine the effects of different compost and rock phosphate doses applications with different mycorrhizal species inoculation on sorghum plant growth and nutrient uptake. Dosages 0, 20, 40 gr compost kg-1 soil as were used a... see more

A swampland has considerable potential in agriculture. This land has high soil acidity level, and high iron content. Therefore, the application of ameliorant to acid sulfate soil is essential to improve the soil and make it more suitable for rice cultivat... see more

Phosphorus deficiency is the major constraint to maize production in acidic soil of Heipang (9°38’, 8°53’) in Northern Guinea Savanna of Nigeria. The soil is high in sesquioxides and soluble aluminum and has high phosphate sorption capacity. To address th... see more

Dissolution of phosphate rock (PR) in soils is a primary concern for P in the PR to be available for plant. The dissolution of three PR materials, China (CPR), Ciamis (IPR) and Gafsa (GPR), in eight acid Indonesian soils (pH in water 4.1-5.7) was tested i... see more

Many of the agricultural soils in Indonesia are acidic and low in both total and available phosphorus which severely limits their potential for crops production. These problems can be corrected by application of chemical fertilizers. However, these fertil... see more

Source of P fertilizer which is used by farmers in upland acid soils area is generally acidulated phosphate rock (PR), such as tripel super phosphate (TSP), super phosphate 36% P2O5 (SP-36), as well as partial acidulated phosphate rock (PAPR) which contai... see more

The aim of this research is to study the approprite formula and applied method of banana corm and phosphate rock on available-P in Alfisols. The research was arranged in factorial completely randomized design with 3 factors. The first factor is the dosage... see more
