Getting it just right: almond growers need to apply the proper amount of nitrogen to their trees, though it's not a problem if you follow these experts' advice

摘要

Nitrogen (N) is of course an essential element for plant growth. In almond trees, it is needed to renew and invigorate the fruiting wood. It is also needed for fruit growth and development. The greatest need for nitrogen occurs when the almond treescome into production. At this time, the demand for nitrogen is driven by fruit development, foliage formation, and tree storage in roots and branches. We must meet the need for nitrogen because a shortage of this element can reduce yields. Most of the nitrogen applied to an almond orchard becomes part of the kernel, hull, and shell. Therefore, the projected yield of an orchard can be used to estimate the need to replace the nitrogen removed in the crop. Apply approximately 1/10 pound of actual nitrogenfor each pound of projected kernel (meat) yield. For examie, if an orchard will yield a ton of meats, apply 200 pounds of actual nitrogen per acre.
