A two-year experiment was conducted in the desert west of the Nile Delta to study the effect of applying fertilizers and other agronomic chemicals through sprinkler irrigation water (a technique refer...
evaluation of Crop effects on runoff and Washout of soil from the surface of agricultural land
water erosion runoff precipitations vegetative cover
2015/3/1
Measurements of the runoff intensity (i.e. its volume and amounts of washed out soil particles) were performed on experimental plots with the slope gradient of 5° within the period of 2004–2008. Exper...
The identification of aluminium-resistance genes provides opportunities for enhancing crop production on acid soils
Acid soils aluminium citrate malate resistance roots tolerance
2015/2/5
Acid soils restrict plant production around the world. One of the major limitations to plant growth on acid soils is the prevalence of soluble aluminium (Al3+) ions which can inhibit root growth at mi...

soil conditions tobacco production
2014/10/28
The area devoted to growing tobacco (Nicotiana tabacum L.) in the province of Granma, Cuba, accounted for nearly 2600 ha in the year 1997, which represented the 4% of the total tobacco plantation area...
Using the DNDC model to compare soil organic carbon dynamics under different crop rotation and fertilizer strategies
crop yield fertilization croplands
2014/10/23
Soil organic carbon (SOC) plays a vital role in determining soil fertility, water holding capacity and susceptibility to land degradation. On the Chinese Loess Plateau, a large amount of crop residues...
