What Is Soil Degradation Soil degradation refers to the loss of land s physical chemical biological and ecological qualities due to either natural or human caused disturbances Some examples of soil degradation processes are the exhaustion of nutrients and organic matter soil erosion acidification desertification and are a number of factors that affect
Plough is used to turn and break the soil and help control weeds and remove the crop surplus It is a tractor mounted implement with a combination of fine blades A hay baler or baler is a piece of agricultural machinery We can use it to compress a cut and raked crop such as flax straw cotton hay salt marsh hay or silage into compact
Agriculture is one of the largest biological sectors that produces the highest biomass which can be an important input for the bioeconomy The AW management AWM based bioeconomic strategies can prevent underutilization of livestock excrement and reckless/random burning of crop residues to ensure food and health security waste
4 Soil preparation before sowing produces seed for the best conditions for seed germination and easy germination of young plants The soil is then plowed to form a small soil structure in which a collection of fine soil is left on the ground to prevent the formation of a crust and a large amount of loose soil is left around the seed and the capillary movement of water is
Frozen soils include both seasonally frozen soil and permafrost The former forms only during the winter in the upper soil and the latter is defined as the ground in which temperatures have remained at or below 0 °C for at least two consecutive years Dobinski 2011; Riseborough et al 2008 Fig 1 Both types of soil are widespread in high latitude and high altitude regions Obu
The paper is centered on the concept of conservation agriculture CA which is defined as a sustainable cultivation system for the future Conservation agriculture CA is a sustainable farming
3 Discing is an essential tillage practice that farmers use for soil preparation It involves the use of a disc harrow which is a piece of farm machinery designed to break down soil clods This process allows water to penetrate more easily and increases soil aeration which enhances the activity of the soil flora and fauna
Small tractors Compact tractors with low horsepower can be used on terraces to perform various tasks such as ploughing tilling and mowing They are designed to navigate tight spaces and hilly terrain Tillers and cultivators These machines are used for breaking up the soil and preparing it for planting

It is used to break clods reduce air pockets press the small stones Tractor is a large vehicle which is used in many agricultural works The tools for land preparation are attached with a tractor which makes them work It is used to lift bulk soil sand stones and in making pits It is also used in soil sampling 14 Hoe This tool
Minimize soil compaction Minimizing compaction is vital in preventing hardpan soil formation Limiting heavy machinery use and avoiding excessive foot traffic on the soil can help reduce compaction Utilizing smaller scale equipment and implementing controlled traffic farming can also help minimize compaction in agricultural operations
Plastics are an additional stressor that potentially harm essential soil functions The widespread use of plastics in crop production has been reported to affect the physical chemical and

Frozen soil refers to all kinds of rock and soil with a temperature below 0 °C and containing ice Lai et al 2013; Ma et al 2009 It is typically classified into three types short term frozen soil seasonal frozen soil and permafrost Cheng 2005 Frozen soil is widely distributed around the world with permafrost covering % of the land area in the Northern Hemisphere
The area of frozen soil accounts for approximately 50% of the Earth s surface and permafrost occupies approximately 25% of the land area of the Northern Hemisphere Zhang et al 1999 In China the area of frozen soil is equivalent to 75% of the land surface Li et al 2008 It is of primary importance to estimate FTF depth accurately
Purpose of Review Ground based mechanized forest operations can cause severe soil disturbances that are often long lasting and detrimental to the health of forested ecosystems To reduce these soil disturbances focus is being increasingly directed at identifying and using appropriate mitigation techniques This systematic review considered 104 scientific
A tractor with a seedbed combination with drill served as a test device Each variant was driven over once with the tractor The wheel load of the rear wheels tyre size 680/75 R 32 was 4100 kg with an inflation pressure of 80 from the control 1 that was not driven over the test variants comprised a variant with no frost 2 a variant with 2 3 cm depth
The fertilizer industry is a source of heavy metals and radionuclides It consists of most of the metals such as cadmium Cd arsenic As mercury Hg nickel Ni lead Pb copper Cu ; natural radionuclide such as U 238 Th 232 and Po 210 FAO 2009; Sönmez et al 2007 Fertilization can be responsible for the accumulation of heavy metal in soil system
Soil is primarily viewed as a critical component of agricultural production in traditional wisdom In more recent years the scientific community has increasingly recognized that soil is also an essential component for environmental protection Obrist et al 2017 climate change mitigation Le Quere et al 2018 ecosystem services Bahram et al 2018 as well as
Frozen soils cover large areas mostly at high latitudes and sometimes altitudes At midlatitude frozen soil can also be expected in winter especially for the morning orbit Dielectric properties of frozen soils are similar to those of dry soil while vegetation

Freeze thaw events are common in boreal and temperate forest ecosystems and are increasingly influenced by climate warming Soil microorganisms play an important role in maintaining ecosystem stability but their responses to freeze thaw cycles FTCs are poorly understood We conducted a field freeze thaw experiment in a natural Korean pine and
