A young cabbage plant exhibiting nitrogen deficiency. 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]
A notable feature of calcium-deficient plants is a defective root system. [14] Roots are usually affected before above-ground parts. [15] Blossom end rot is also a result of inadequate calcium. [16] Calcium regulates transport of other nutrients into the plant and is also involved in the activation of certain plant enzymes.
Plant nutrient deficiencies can be avoided or corrected using a variety of approaches including the consultation of experts on-site, the use of soil and plant-tissue testing services, the application of prescription-blend fertilizers, the application of fresh or well-decomposed organic matter, and the use of biological systems such as cover ...

[ 3 ] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
The formulation of hydroponic solutions is an application of plant nutrition, with nutrient deficiency symptoms mirroring those found in traditional soil based agriculture. However, the underlying chemistry of hydroponic solutions can differ from soil chemistry in many significant ways. Important differences include:
[19] [20] Cannabis x intersita Sojak, a strain identified in 1960, is a cross between C. sativa and C. ruderalis. [3] Attempts to produce a Cannabis strain with a shorter growing season are another application of cultivating C. ruderalis. [8] C. ruderalis when crossed with sativa and indica strains will carry the recessive autoflowering trait ...
