What Are The Different Branches Of Agriculture – Soil science is a discipline that deals with the study of soil as a natural resource for plant growth. What is soil?
From an agricultural perspective, soil is the unconsolidated upper part of the earth’s crust that serves as a natural medium for the growth of terrestrial plants. In short: soil is the habitat of plants.
What Are The Different Branches Of Agriculture
But different branches of science define soil differently, for example, a geologist or mining engineer might call it “broken rock or debris covering rocks,” and an engineer might call it “soil or material for houses.” and roads”; and an economist might call it “land.”
Sustainable Development Of Agriculture: A System Dynamics Model
Soil science is an applied scientific discipline of a holistic nature due to its interrelationship with many other sciences.
It refers to soil-dwelling organisms and their biology, functions and activities. For example, insects and nematodes.
This field deals with primary and secondary soil minerals and their role in soil chemistry, physics, fertility and biology and their relationship to soil formation.
Soil genesis deals with the weathering of rocks and minerals, the factors and processes of soil formation, and soil classification is the systematic rearrangement of soils into groups or categories.
Name The Branch Of Agriculture That Deals With Cultivation Of Fruits, Vegetables, Flowers And Ornamental Plants
It deals with the mechanical behavior of soil mass ie. physical properties of soil, focusing on the transport of substances, especially water and energy, into the soil.
This applies to excess oil soluble salts, their recovery and soil treatment for saline agriculture.
Soil testing deals with the systematic examination, description, classification, mapping, and interpretation of soils in the field and laboratory in terms of their suitability for various farming systems.
It deals with protecting the soil from physical loss due to erosion (wind and water) or chemical damage. Therefore, soil conservation combines all farming and land use methods to protect the soil from damage caused by natural or human factors.

Crop Diseases: How To Identify, Control, And Prevent

Lipins are versatile enzymes that catalyze a variety of reactions. Furthermore, lipases are the most widely used class of enzymes in biotechnology and organic chemistry. Lipids can be produced by many organisms, including animals, plants, and microorganisms. Microbial lipases are more stable, substrate specific and have lower production costs than other sources of these enzymes. Although commercial lipases are widely used as biocatalysts, there are still many challenges in the production of microbial lipases using renewable sources such as straw, corn, cake oil, and industrial wastewater as the main component of microbial culture. Submersible fermentation (SMF) and solid phase fermentation (SSF) are two important technologies for lipase production by microorganisms. Therefore, this review focuses on microbial lipases, particularly their function, specificity, types and production technology, including the use of renewable agro-industrial residues and waste materials.
Lipid or triacylglycerol acyl ester hydrolases belong to the family of serine hydrolases and are called carboxylic acid esterases (CE 184.108.40.206). Claude Bernard discovered the first use of lipase in 1848. His first major scientific discovery was that the pancreas produced a substance that emulsified and saponified fats. This discovery not only explains part of the exocrine function of the pancreas, but also the mechanisms of fat digestion and absorption . Lipids can be used by a variety of organisms, including animals that use organs such as the pancreas, liver, stomach, and intestinal wall, as well as the seeds and vegetative organs of plants and microorganisms . Microorganisms such as bacteria  , fungi  , and yeasts can produce intracellular, extracellular, or membrane-bound lipase. In addition, microbial lipases are more stable, have substrate specificity and have lower production costs compared to other sources of these enzymes [6, 7, 8]. Eikmannin  isolated the first microbial lipases from Bacillus prodigiosus, Bacillus pyocyaneus, and Bacillus fluorescens, now Serratia marcescens, Pseudomonas aeruginosa, and Pseudomonas fluorescens.
// The β hydrolase layer is constructed with a lip, consisting primarily of eight parallel β-strands surrounded by α-helices that modify a central supercoiled β-sheet. In addition, some changes in the α/β fold have been found in some lipases, consisting of differences in the size of α-shells or β-sheets and loop length . The primary catalytic site of lipase is a region with the sequence G-X-S-X-G, where G = glycine, S = serine, and X = any amino acid. The catalytically active part of lipase is found not only in lipase but also in other hydrolytic enzymes such as serine hydrolases . The main structural parts of lipase include an envelope, a binding pocket, an oxyanion hole, and a difide bond. The envelope consists of one or more α-chains linked by a flexible structure to the core structure of the enzyme. The gate is a transposable element and can open the active site upon reaction of the two-step system. The active site of the enzyme is a cap that allows access to the reaction substrate . The binding pocket is the active site of lipases and is located on the central sheet of the protein structure. Lipase substrate binding sites differ in size, shape, pocket depth, and physicochemical properties of amino acids. Three types of pocket geometry can be distinguished: hydrophobic cleft, functional or tunnel-like. The lip of Rhizopus and Rhizomucor has a cleft-like hydrophobic binding site located on the protein surface. Burkholderia spp. produced lipases have a functionally similar binding site, and, for example, a lipase from Candida rugosa has a tunnel-like binding site . The oxyanion hole affects the catalytic efficiency of the enzyme. This important component greatly affects hydrolysis because during the reaction the oxyanion hole stabilizes the charge distribution and lowers the energy of the tetrahedral intermediate state by forming hydrogen bonds. Lipases are also characterized by the presence of difide bridges, which provide enzyme stability and are often important for their catalytic activity . The structure of Bacillus subtilis lipase (Lip A) is shown in Figure 1.

The classification of lipases is based on the source and specificity of these enzymes (Figure 2). Lipolytic microorganisms are found in many oil-contaminated areas, such as oil-contaminated soil, vegetable oils, dairy waste, and spoiled food . Lipids are widely distributed in animals, plants and microorganisms, and their main role is in lipid metabolism . Animal lipase is mainly derived from the pancreas
