Some intensive farms can use sustainable methods, although this typically necessitates higher inputs of labor or lower yields. [2] Sustainably increasing agricultural productivity , especially on smallholdings , is an important way to decrease the amount of land needed for farming and slow and reverse environmental degradation caused by ...
Intensive crop farming is a modern industrialized form of crop farming.Intensive crop farming's methods include innovation in agricultural machinery, farming methods, genetic engineering technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, patent protection of genetic information, and global trade.
Soil chemistry – study of the chemical characteristics of soil. Soil amendment – material added to soil to improve plant growth and health. Soil erosion – process by which soil is removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations.
The ratio of two extensive properties of the same object or system is an intensive property. For example, the ratio of an object's mass and volume, which are two extensive properties, is density, which is an intensive property. [9] More generally properties can be combined to give new properties, which may be called derived or composite properties.
The constant fish movements allow for the loosening of the surface soil which can: Improve oxygen levels by increasing the amount of dissolved oxygen. [ 8 ] Consequently, the activity of microorganisms is increased and they generate more usable nutrients, which will allow an increased nutrient uptake for the rice.
In addition, selected minerals or nutrients such as iron can be added in addition to the fish waste that serves as the main source of nutrients to plants. [33] A good way to deal with solids buildup in aquaponics is the use of worms, which liquefy the solid organic matter so that it can be utilized by the plants and/or other animals in the system.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
So plant roots can not penetrate deep into the soil for optimum growth in Alkali soils. When soil is irrigated with low pH / acidic water, the useful salts (Ca, Mg, K, P, S, etc.) are removed by draining water from the acidic soil and in addition unwanted aluminium and manganese salts to the plants are dissolved from the soil impeding plant ...
