      The soil mass is then reinforced by the resulting grout column, reducing settlement and increasing shear strength. Grout utilized typically consists of Portland cement, sand, and water. Natural fine-grained soils, fly ash, or bentonite can be added to the mix. Generally, the grout strength is not critical for soil improvement. Background and Objective: The dairy industry in Saudi Arabia is producing huge quantity of Farm Yard Manure (FYM) resulting in potential environmental and health hazards. Raw FYM is processed into usable compost for increasing soil fertility and productivity. The main aim of this study was to analyze the effect of prepared Cow Manure Compost (CMC) on chemical and microbiological soil properties.

      The M treatment can accelerate soil carbon and nitrogen circulation and improve soil quality, with enzyme activities stemming from manure compost. As manure compost contains abundant organic matter, it can drastically increase SOM by providing a rich source of carbon and nutrients for enzyme production microorganisms. Hence, a study was planned to evaluate combined use of organic and inorganic amendments for better rehabilitation of salt affected soil in ricewheat cropping sequence from to Treatments included T 1 - control, T 2 - gypsum @ SGR, T 3 - CaCl 2 @ 50% SGR, T 4 - CaCl 2 @ 50% SGR + biogas slurry @ 10 tˑha -1, T 5 - H 2 SO 4 @ 25%.

    Based on the characters of coastal saline-alkali soil in Yellow River Delta, four kinds of soil with the total salt content of %, %, %, % respectively, were used as the research objects in this study. Leaching experiment of soil improvement were operated by using flue gas desulfurization gypsum and humic acid as the soil amendments through single or combined application. An excellent summary of the general nature of the problem, including information on the origin and nature of saline and alkali soils, effects on crops, types of information required for diagnosis, and principles and practices of reclamation. Methods for making tests and analyses are given in a separate section.

(physical and chemical) of sodic soil and the resultant impact on wheat crop. (gypsum + manure) treatment. Soil treatment can be used to make contaminated soil usable for agriculture and other purposes. If soil contains chemicals or wastes such as oil, alkali or some other non-degradable material, this can be treated using microbes.

Soil contamination can be caused by a number of activities, such as the inappropriate disposal of industrial waste, sewage, agricultural chemicals, and so on. Organic amendments may promote plant growth and enhance saline alkali soil remediation in salt-tolerant plant cultivation practices.

Conclusions. The application of organic amendments to saline alkali soil improved the nutrient content of soil, which could directly promote the growth of salt-tolerant plants.

The following types of organic matter attract microorganisms that speed up soil improvement by developing tunnels (more aeration) and pooping a lot (more organic matter to break up the tightly wound clay particles).

Some Amendments to Consider for Clay Soil. Compost: Homemade compost is an excellent soil conditioner that improves drainage. In experiments by Verma and Abrol ( a,b) the soil improvement in pyrite plots did not approach the improvement obtained in gypsum treated plots even three years after the amendments were applied.

These results tend to show that the efficiency of sulphur compounds that must oxidize to produce sulphuric acid before they can replace adsorbed. Because clay soil can become compacted easily, place about 3 to 4 inches ( cm.) of the chosen soil amendment on the soil and work it gently down into the soil about 4 to 6 inches ( cm.).

In the first season or two after adding organic material to the soil. Besides, there is a general soil and ecological improvement through microbial activity and moderation of the micro-climate.

Bulky organic manures: Farm manures has been successfully tried in the treatment of saline-alkaline soils in Haryana and Punjab. Sodic and alkali soil amelioration primarily involves increasing calcium (Ca 2+) on the cation exchange complex at the expense of Na +.

Soil amelioration, Chemical amendments, Gypsum. yard manure has shown significant improvement in carbon status of soil. The highest Oxidizable carbon was recorded under BBF with gypsum treatment T4 ( mg kg-1) at depth of soil as well as ( mg kg-1) cm depth of soil.

The highest water soluble carbon was also recorded under. The amendments were applied to soil and mixed thoroughly with the upper 20 cm layer. The used amendments were subjected to some chemical analyses as shown in Table El-Baqar drain water was used for irrigation to bring the soil to field capacity and the soil was left in the air temperature ( ± °C) for 15 days before cultivation of plant for equilibrium.

Bull. 22, (). When to Improve Garden Soil With Amendments. The best time to amend garden soil is when you're first establishing a garden bed. In an existing garden, soil amendments typically are an ongoing task, even if it's as simple as digging in some compost prior to each year's plantings.

If your plants are growing well, there's usually no need to touch the soil. Alkali or sodic soil is defined as a soil having a conductivity of the saturation extract less than 4 dS m-1 and an exchangeable sodium percentage greater than The pH is usually between – Most alkali soils, particularly in the arid and semi-arid regions, contain CaCO 3 in the profile in some form and constant hydrolysis of CaCO.

Alkali, or Alkaline, soils are clay soils with high pH (> ), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at to 1 metre depth.

Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate, which causes the soil to swell and difficult to clarify/settle.

Regardless of soil amendments, increasing soil salinity as shown in highly saline soil had an adverse effect on soil bulk density, HC, OM and AW. In addition to. Saline-alkali soil is widely distributed in arid and semiarid areas due to extremely low precipitation and strong evaporation 1, the arid area of northwest China, saline-alkali soil covers.

Amend the soil depending on the results of the test. Most clay soils are on the alkaline side, meaning that you'll probably want to lower the pH of the soil. There are several ways to do this. The most common substances to add to clay soil are builder's sand, gypsum, composted manure, compost or other coarse organic : K.

soil condition. Manure should be leached of the excessive salts to avoid injury to plants. Gypsum is often recommended to improve clay soil. It is beneficial for sodic (alkali) soils, Gypsum and Other Chemical Amendments for Soil Improvement.Organic amendments co-applied with chemical amendments seemed to have a high value for reducing soil pH, soil salinity, and soil sodicity: Municipal wastewater: EC 60 mScm −1 pH Decreasing soil pH and bulk density, while increasing EC and OM content of soil: Farm yard manure: EC – mScm −1 pH –KEYWORD: Manure, Nitrogen, Organic amendments, phosphorus, potash, sodic land.

INTRODUCTION Salt affected soils in India have been classified into either (a) alkali or sodic and (b) saline. Alkali soils have excess of carbonates and bicarbonates, high pH and ESP, poor soil physical properties and low organic matter content.
