There was an area in the garden where I had concerns that the soil is deficient in some nutrients because of the slow growth. This pepper plant for example was growing quite slowly compared to the one I had in the pot (with different soil) and had only one pepper till now.
Based on observation and reading the books, it could be following of two things:
- The soil was acidic and therefore nutrients could not be easily absorbed.
- There was nitrogen deficieny, as indicated by slow growth and yellowing of the older leaves at the bottom.
I used the following kit to test the soil. It provides pH, and NPK tests in a easy way. I sampled the soil as written in the instructions. The soil needs to be mixed with water and the solution is transferred to these test and reference chambers. The test was quite fast and following were the results. The pH indication was neutral, P and K were adequate where as N was deficient.
You can see it from the colour of the solution after the powder in the capsule was mixed.
Based on these results I decided to move the pepper plant to a different area.
I will check in few days if the plant recovers or not.
