A healthy, fast-growing barley crop, fully supported by fertilizer, makes more efficient use of water to maximize yields.
Yara’s crop nutrient recommendations – such as those presented on this web site – help the crop make more productive use of water through encouraging strong growth and high yields leading to more transpiration and less drainage and direct evaporation.
Regular fertilizer use will encourage rooting, ensuring better extraction of water from the soil.
Well-balanced nutrition also maximizes leaf efficiency, providing a strong canopy that reduces soil evaporating by creating shade across the grove for a longer period.
Potassium (via its osmotic function) and nitrogen (as a result of the internal regulation of hormones and xylem pH) are important for efficient and optimal regulation and control of CO2 uptake and water loss through the stomata.
Finally, by using comprehensive, tailored, fertilizer programs that ensures no nutrient is lacking, yield is increased, thereby producing more fruit for every mm of rainfall or irrigation water that is applied.
At low nitrogen supply water requirement to produce one kilogram of grain is much higher than at adequate N rates.
