Soil structure is essential to soil health and fertility; soil structure decline has a direct effect on soil and surface food chain and biodiversity as a consequence. Continued crop cultivation eventually results in significant changes within the soil, such as its nutrient status, pH balance, organic matter content, and physical characteristics ...
Biodiversity is the measure of biotic and abiotic diversity in an ecosystem, described by heterogeneity. [1] The loss of biodiversity in agriculture has been an increasing issue since the global increase of food demands and success of popular crops. [3] [4] This loss of heterogeneity declines species biodiversity on agricultural lands. [5 ...
Other important soil organisms include nematodes, mycorrhiza and bacteria. A quarter of all the animal species live underground. According to the 2020 Food and Agriculture Organization’s report "State of knowledge of soil biodiversity – Status, challenges and potentialities", there are major gaps in knowledge about biodiversity in soils ...
For example, the means-based analysis might look at pesticides and fertilization methods that farmers are using, and effect-based analysis would consider how much CO 2 is being emitted or what the nitrogen content of the soil is. [4] The environmental impact of agriculture involves impacts on a variety of different factors: the soil, water, the ...
Aquatic diversity is an important component of agricultural biodiversity. The conservation and sustainable use of local aquatic ecosystems, ponds, rivers, and coastal commons by artisanal fisherfolk and smallholder farmers is important to the survival of both humans and the environment.
In contrast, the molecular examination of 17,516 environmental 18S rRNA gene sequences representing 20 phyla of soil animals covering a range of biomes and latitudes around the world indicated otherwise, and the main conclusion from this study was that below-ground animal diversity may be inversely related to above-ground biodiversity.
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance (i.e. no-till farming), maintenance of a permanent soil cover, and diversification of plant species.
Fig. Concept of Soil Health Gap. The importance of soil for global food security, agro-ecosystem, environment, and human life has exponentially shifted the research trends toward soil health. However, the lack of a site/region-specific benchmark has limited the research toward understanding the effect of different agronomic managements on soil ...
