Nitrogen deficiency is a deficiency of nitrogen in plants. This can occur when organic matter with high carbon content, such as sawdust, is added to soil. [1] Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants. [1] This is known as "robbing" the soil of nitrogen.
[a] This subgroup of the rosids encompasses 28 families of trees, shrubs, vines and herbaceous perennials and annuals. The roots of many of the species host bacteria that fix nitrogen into compounds the plants can use. [4] [5] The trees of this subgroup dominate many temperate forests. [6]

The Food and Agriculture Organization of the United Nations (FAO) estimates world demand for nitrogen fertilizers increased by 1.7% annually between 2011 and 2015, an increase of 7.5 million tonnes. Regional increases of nitrogen fertilizer use are expected to be 67% by Asia, 18% by the Americas, 10% by Europe, 3% by Africa, and 1% by Oceania. [5]
Tree farm systems in each state are self-governing and all work under specific guidelines developed by the ATFS's National Operating Committee. The term tree farming was introduced in 1940 by linking the terms in an attempt to make it easier for the public to conceptualize that trees are renewable resources.

The Louisiana Department of Agriculture and Forestry (LDAF) is a state agency of Louisiana, headquartered in Baton Rouge. The Department is responsible for promoting, protecting and advancing agriculture and forestry, and soil and water resources.

Fertilizer trees are used in agroforestry to improve the condition of soils used for farming. As woody legumes, they capture nitrogen from the air and put it in the soil through their roots and falling leaves. [1] They can also bring nutrients from deep in the soil up to the surface for crops with roots that cannot reach that depth. [2]
