The history of framing cannabis production as an issue of drug use has suppressed discussion about cannabis production as a massive agricultural sector. [2] In places where cannabis is legal to product, discussing environmental impact is still challenging because so many other issues related to cannabis distract from the conversation. [2]
In 2012, it was estimated that at least 3,177,241,050 gallons of water were used in the production of marijuana in California. [2] Thus, marijuana production can have severe implications on watershed levels with a number of organisations calling for stricter regulations as marijuana becomes more widespread.
Empirically derived NDVI products have been shown to be unstable, varying with soil colour, soil moisture, and saturation effects from high density vegetation. In an attempt to improve NDVI, Huete [1] developed a vegetation index that accounted for the differential red and near-infrared extinction through the vegetation canopy. The index is a ...
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.
The Storie index is a method of soil rating based on soil characteristics that govern the land's potential use and productivity capacity.Developed by R. Earl Storie at University of California, Berkeley in the 1930s as a method of land valuation, it is independent of other physical or economic factors that might determine the desirability of growing certain plants in a given location.
The BBCH-scale (weed) identifies the phenological development stages of weed species. It is a plant species specific version of the BBCH-scale. D = Dicotyledons G = Gramineae M = Monocotyledons P = Perennial plants V = Development from vegetative parts or propagated organs No code letter is used if the description applies to all groups of plants.
The normalized difference vegetation index (NDVI) is a widely-used metric for quantifying the health and density of vegetation using sensor data. It is calculated from spectrometric data at two specific bands: red and near-infrared.
6- monthly NDVI average for Australia, 1 Dec 2012 to 31 May 2013 [1]. A vegetation index (VI) is a spectral imaging transformation of two or more image bands designed to enhance the contribution of vegetation properties and allow reliable spatial and temporal inter-comparisons of terrestrial photosynthetic activity and canopy structural variations.
