Abstract The rising population is increasing food demand, yet actual crop production limited by the poor efficiency of classical fertilizers. In particular, only about 40–60% fertilizer nitrogen, 15–20% phosphorus and 50–60% potassium are used plants, rest ending polluting environment. Nanofertilizers promising alternatives. Here, we review plant nutrients, synthesis zinc oxide nanoparticles, e...

Balanced nutrients are essential for healthy plant growth, but there is no sensor available to monitor such as N and K. Electrical conductivity (EC) one of the key parameters that could be adopted nutrient contents because soil EC influenced by nutrients. Therefore, main objective this study was examine effects different basal fertilizers, including inorganic, organic, compost application ratio...

Two field experiments were conducted in Aly Mubark experimental Farm in sandy soil at El-Bustan Sandy soil irrigated by drip irrigation, during 2003 and 2004 seasons. The experiments aimed to study the effect of three irrigation treatments with three different kinds of fertilizers and its concentration on sage growth, yield, essential oil yield and components, macro-nutrients content in dry her...

Poultry litter application to fields that will be cropped to legumes is desirable because legumes biologically fix N2 gas from the atmosphere, allowing manures to be applied at rates needed only to satisfy crop P and/or K requirements. The need to export the nutrients in poultry litter from western Arkansas to areas of intensive cropping and fertilizer use plus recent increases in commercial fe...

What is micro nutrient testing? Although not all the same, these tests are fundamentally a measure of the body’s essential micro nutrients, usually taken from a blood test but can be from urine, sweat, hair, saliva or even toe nail clippings! A vast array of nutrients can be analysed but the most important and relevant have been collated in the recently developed Cancer Risk Nutritional Profile...
