It has recently become popular to use for growing seedlings shoplifter ground. Many believe that the need for seedlings depleted sterile substrate and that the seedlings do not need any nutrients.
But then the fun begins... Seedlings grow the puny, the sores on her attack... Start talking about that for the strength of the seedlings need to be sure to feed her the superphosphate, the potassium sulphate or calcium, the urea, the calcium nitrate. My question is: WHY? Why sow plants in the "no" sterile soil, and then stuff them any chemistry ???
After seedling that grows into a good medium, receives plenty of light and proper watering, will never get sick and wither. I never buy the ground for planting. For its cultivation using only soil from your same region + biocompost own same preparation, which was attended not only beneficial microorganisms, but also earthworms. About how I'm doing this healthy and useful for rastishek compost, I already wrote earlier here.
And what's the point of using a sterile substrate? Immunity plants do not arise out of nowhere with zero. Well, we grow plants in a sterile environment... We are fed up with what is not in the lean sterile substrate, and even in an unusual form of plants... then planted them in their gardens... so, what is next? And then there Rastishka his forehead with entirely new conditions for them: the new PH environment, unknown to them, micronutrients, microbes (beneficial and harmful), diseases, etc. etc.
And it starts from the poor rastishek new period of adaptation and survival. It takes some time, and not the fact that each plant to deal with it, because the immune system is zero. And you need not only to get used to new conditions, and still have time to build up, and root system and leaf apparatus... and certainly not the fact that such a plant in the future will give their full genetic potential of the formation of the crop.
Maybe I do not understand something wrong, because in its opinion do not insist. But in at least their yields are not complaining. And, subsequently, be sure to clearly show you all the results of the current season. I'll look forward to your comments with your opinion about the above.
