Soil science helps us understand its aspect be it biological, physical or chemical composition in relation to plants or vegetable production in greenhouses and open field farming. We at hortitechno produce and services ensures that we test and understand the soil before we do any work.

 We do soil testing to understand the microbes living in the soil, we do have helpful and harmful . The solanaceae family that we have tomato, capsicum, egg plant , Managu e.t.c is affected by a bacteria causing wilting. When we do testing of the soil and finds this bacteria its advisable for farmer to do soil sterilization to kill the bacteria and pot the sterilized soil to prevent contamination.

Methods of sterilization.


Soil sterilization using steaming is the most reliable way since wee retain the chemical composition and the physical structure of the soil. This is done by using heated water steam that is directed in air tight covered soil and it takes eight hours to be fully sterilized.


Soil frying is also another common way people use in sterilization, it also does kill the pathogen the only dis advantage it has is change of chemical and physical properties of the soil . the methodology is done by putting soils in pan and placing the pan on heat, during heating the soil is mix over and over for uniform distribution of heat.


Chemicals are also used to do soil sterilization mostly in flower farms, for vegetables and fruits we tend to discourage this method. When not done properly it can leave residue on the final product.

All this methods work and the best is  soil steaming, at greenhouse Kenya we always make sure you plant on good soil.
