we are in process of making organic fertilizer to improve crop production. we use different things but has difficulty to maintain pH. we want to add something which completely natural and increase pH also? kindly provide suggestion for what should add in fertilizer to increases or maintain pH

If organic fertilizers have low pH than what we should add in to maintain pH in 6-7 range?

Adding agricultural lime is the normal and cheapest way to increase the ph. of soils, or soilless media. Although it is slow acting; it is efficient, and relatively insoluble, so its effect lasts for years, rather than months.

I believe that, the best way to solve this problem is adding Charcoal since it has many possible benefits not only on crop production but also on soil includes soil pH.

If an organic fertilizer is having a low pH, ( how much low , you have not mentioned ), it is good for soil having alkaline pH more than 7.0. Some punchline is missing from your question , please elaborate more on the content of your question . What is the pH of your organic fertilizer and to what kind of soil s, you are looking to apply.

Excellent reply by Dr. Anoop. Low pH organic fertilizers are great for Alkaline soils of arid regions. In the case of acid soils, really depends on what is the pH of organic fertilizer and the soil.
