The latter can be caused by incorrect pH, shortage of water, poor root growth or an excess of another nutrient. [6] 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 ...

An abundance of one nutrient may cause a deficiency of another nutrient. For example, K + uptake can be influenced by the amount of NH + 4 available. [6] Nitrogen is plentiful in the Earth's atmosphere, and a number of commercially-important agricultural plants engage in nitrogen fixation (conversion of atmospheric nitrogen to a biologically ...
Citrus greening was first found in 2005 in the US and has cut the orange tree production in half [2] [3] Citrus greening disease [4] (Chinese: 黃龍病; pinyin: huánglóngbìng abbr. HLB) [5] is a disease of citrus caused by a vector-transmitted pathogen. The causative agents are motile bacteria, Liberibacter spp.
Cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ. In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales.

In hydroponic growing, the nutrient solution is best at 5.2 to 5.8, making Cannabis well-suited to hydroponics because this pH range is hostile to most bacteria and fungi. [ citation needed ] Tissue culture multiplication has become important in producing medically important clones, [ 19 ] while seed production remains the generally preferred ...
