Sulphate of Potash

Potash solubility

SOP

Sop is widely used potash fertilizer in Pakistan. Its chemical formula is K2SO4 and it contains 54% K2O and 18% S, if pure. But for commercial use it is available with 50% K2O and 18% S, as it contains some impurities like

Magnesium

, ammonium, sodium and chlorides.
Its solubility is 115 g/litre of water at room temperature. If SOP then solubility of all brands is same. If some fertilizer company claims more soluble SOP then it is not pure SOP. It may be powdered MOP or blend of MOP and

ammonium sulphate

 (both have higher solubility).
There is no SOP of higher solubility, so don't waste your money on buying costly SOP which is assumed more soluble, because that is not SOP.

How to Loosen Hard Soils

Hard soil

If your land is tough and the crop is not good in your land, then you should test your land, which you will find out which alignments are higher and what is lower in your land. From which you can make a schedule for fertilizers in your land

Soil Treatment

Loosen hard soil

Main reason of hardness is presence of excessive amount of sodium. Sodium is monovalent atom having one positive charge, Na+, it attaches itself with negatively charged clay particle. In this way its charge is balanced and cannot attract another clay particle, due to which soil changes to very fine particles, causing fine structure. When dried these fine particles form very compact arrangement causing hardness of soil. Other reasons include geological aspects, high pH, less organic matter and soil compaction due to use of heavy machinery.
#Treatment ;
There are different ways to remove sodium from upper layer of soil and to make it porous and loose.

Plant treatment

1. Deep plough with chezel twice and then level land. Now fertigate calcium nitrate or calcium chloride 30 to 50 kg/acre. Keep standing water in this field for 3 to 4 days. Calcium nitrate and calcium chloride have readily available calcium which will effectively detach sidium from soil and sodium will leach down with water. Calcium is divalent atom Ca++, so it has more attraction for soil particles as compared to sodium. It will remove sodium and will take its place. Then due to divalent nature it will aggregate soil particles which will loosen soil and after one week of treatment soil structure will be much better. This is a quick way to reclaim soil.

2: Dig a hole on one side of affected acre upto level of sand of size 5x5 feet. Level your land, give 2 to 3 ploughing. Then flood it upto 6 inches, most of sodium will dissolve in water. Then after half hour remove this salty water out of field into hole. Repeat this process after 10 days. Take gypsum stones and place in front of tube well delivery. It will slowly add calcium which will further assist in reclaiming.

Sulphur

Along with above practices, always use acidic fertilizers, 20 kg sulfur in each crop, organic matter in form of compost, green manuring whenever possible, and chezel plough atleast once in a year will make your soil much more rich, loosen and well structured.

How to Adjust Soil PH

Soil pH measures how alkaline or acidic the soil is. The pH scale is from 0 to 14 with neutral being 7 on the scale. Acidic soil is anything with a pH value less than 7 and alkaline soil is anything with a pH value over 7.

Plant Growth

The quality of plant growth and reproduction is affected by the pH level of the soil and the requirements vary depending on the plants themselves. The pH value is directly related to how available nutrients in the soil are for the plants. Different plants require different pH levels. Azaleas and blueberries are at their best in acidic soils with a pH between 5 and 5.5. Grasses, ornamental flowers, and vegetables prefer a slightly acidic soil with a pH between 5.8 and 6.5. Nutrient deficiencies may result of the soil pH is above or below the recommended range.

Soil pH

Three are 3 categories of nutrients

required for healthy, productive plants and vegetables. Nitrogen, phosphorus and potassium are the primary nutrients and are needed in much larger quantities than other the secondary or micronutrients. The secondary nutrients, magnesium, sulfur, and calcium are needed in much smaller quantities but are still very important to the health of the plants. The micronutrients, manganese and zinc are required in small amounts. For the most part secondary and micronutrients can be controlled by maintaining the soil pH at the proper level. The primary nutrients are controlled by adding fertilizer.



Plant growth is impacted by the availability of nutrients which is affected by the extremes of the pH. Some nutrients become toxic to plants when they are more available to them such as aluminum or manganese in highly acidic soils. At low pH values, calcium, phosphorus and magnesium become less available for the plant to take up. When the soil pH is above 6.5, most of the micronutrients are less available to the plants.

Several things factor in to the level of pH in the soil. Soil formed by basic rocks typically has a higher pH than soil formed by acid rocks.

If soils are formed in high rainfall areas they will be more acidic than those formed in dry areas. This is due to the rainfall leaching nutrients from the soil and depositing aluminum and iron which are acidic. Decomposing organic matter and fertilizers containing ammonium or urea increase the acidity of the soil.

To increase the soil pH value ground limestone is commonly used. How much limestone is needed to raise the pH value depends on several things including how much organic matter there is and the texture of the soil. Typically the more clay there is in the soil the more limestone will be required to adjust the pH value of the soil.



You should always have your soil tested prior to trying to make any adjustments. Your local Agricultural Extension Agency should be able to provide you with soil testing services and a detailed report. Have your soil tested in the fall and add the required amount of limestone 2 or 3 months before planting.

Wood ashes

are also used to raise the pH of the soil although they are not as effective as limestone. Work small amounts of wood ash into the soil during the winter months.

If you need to lower your pH, based on a soil test, apply sulfur or aluminum sulfate. Sulfur will convert over time into sulfuric acid taking longer to affect the pH than aluminum sulfate which works instantly.
