Crop rotation and cover crops prevent soil erosion, by protecting topsoil from wind and water. [32] Effective crop rotation can reduce pest pressure on crops, provides weed control, reduces disease build up, and improves the efficiency of soil nutrients and nutrient cycling. [128] This reduces the need for fertilizers and pesticides. [127]
The word pesticide derives from the Latin pestis (plague) and caedere (kill). [5]The Food and Agriculture Organization (FAO) has defined pesticide as: . any substance or mixture of substances intended for preventing, destroying, or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the ...
The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
A crop is a plant that can be grown and harvested extensively for profit or subsistence. [1] In other words, a crop is a plant or plant product that is grown for a specific purpose such as food, fibre, or fuel. When plants of the same species are cultivated in rows or other systematic arrangements, it is called crop field or crop cultivation.
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 ...
From 1891 to 1946, the annual growth rate of all crop output was 0.4 %, and food-grain output was practically stagnant. There were significant regional and intercrop differences, however, nonfood crops doing better than food crops. Among food crops, by far the most important source of stagnation was rice.
The IAPPS was founded in 1946 during the first International Plant Congress in Louvain, Belgium. The first president of the organisation was Olaf Freyberg of Malmö, Sweden, who made the following comment: The world needs a plant protection organization, and not only to plan future congresses, but much more provide a platform for the discussion of current research results amongst scientists.
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.
