Applying and Optimizing Water-Soluble, Slow-Release Nitrogen Fertilizers for Water-Saving Agriculture

Water-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes

The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...

Mechanisms underlying plant resilience to water deficits: prospects for water-saving agriculture.

Drought is one of the greatest limitations to crop expansion outside the present-day agricultural areas. It will become increasingly important in regions of the globe where, in the past, the problem was negligible, due to the recognized changes in global climate. Today the concern is with improving cultural practices and crop genotypes for drought-prone areas; therefore, understanding the mecha...

New Development In Slow-Release Fertilizers

There have been several recent developments in slow-release fertilizers. These materials supply nutrients continuously over an extended period in contrast to water soluble fertilizers which are immediately available after incorporation in moist soil. Slow-release fertilizers are not subject to rapid leaching loss and do not easily burn plants from over-application. The major need for slow relea...

Systemic Signaling Under Water Deficit Condition and Its Exploitation in Water Saving Agriculture

Role of Slow-Release Nanocomposite Fertilizers on Nitrogen and Phosphate Availability in Soil

Developing efficient crop fertilization practices has become more and more important due to the ever-increasing global demand for food production. One approach to improving the efficiency of phosphate and urea fertilization is to improve their interaction through nanocomposites that are able to control the release of urea and P in the soil. Nanocomposites were produced from urea (Ur) or extrude...
