Recent studies have revealed that the integrated use of organic and inorganic fertilizers on crop has not received adequate research attention. In this paper, maize is considered among the most important cereal crops in Nigeria and all over the world that has high requirement for organic and inorganic nutrients in order to obtain good quality and high yields. The application of inorganic fertil...

Dr. Alex Shigo, noted tree expert, often speaks about an industrywide fallacy that we can "feed" trees, shrubs, turf and other plants. In reality, plants manufacture their own food through photosynthesis. Elements from the air, water and soil are combined and altered in order to provide the starches plants use for energy and growth. Therefore, we cannot feed a plant. What we can do is provide a...

The growth of the human population is causing an exponential increase in need for food. Fertilizers are one most important elements to meet this increased demand and ensure global food security. Many enhanced efficiency fertilizers, such as controlled-release fertilizers (CRFs) have been developed. Although these offer many advantages over prior generations, their high cost production well unfa...

Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

Farmers are increasing the use of fertilizers in chestnut, only cash crop produced mountainous areas northeastern Portugal. This calls for more studies to guide them towards a ecological intensification. The effects three controlled-release fertilizers, two that release nutrients over months (BoskGrow 20:05:20_3m, Exactyon 18:05:13_3m) and one six (Exactyon 18:05:12_6m), an organic amendment au...

Controlled-release fertilizers are interesting alternatives to current commercial chemical fertilizers, which present a higher nutrient release rate, and can negatively impact the ecosystem. In this work, two urea controlled-release fertilizer types were manufactured from carnauba wax (CW), granulated (U), natural sodium bentonite (Bent-R Bent-Na, respectively). first type, mechanochemical meth...

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...
