"soil exhaustion is occurring after repeated cultivation of a certain group of plants lost the suitability of the soil, enabling plants of this group of normal growth
of fruit trees.
the internodes are compressed,
crown shoots are weak,
strain amplitudes are .. vigorously developed
the root tips are thickened club-like
These symptoms resolve after transplanting to healthy soil
nurseries need for growing fruit trees, always fresh ground
There are several theories:
organisms theory -
microorganisms, nematodes (for agriculture at. crop rotation very important)
toxin theory -
in the root horizon it comes to the accumulation of poisonous substances (favorite fruit structurally)
The documents are different species and sensitive
varietal differences were not detected.
pome fruit, peach, cherry - direct replica not available 20 years ago,
apricot, almond plum - not direct replica from 4 - 5 years,
core of stone fruits and vice versa is usually possible after clearing.
2008 there was a conference for the establishment of fruit trees in the open countryside in Müncheberg, where among others was reported on the nutrient consumption of crop, and fruit trees.
In Müncheberg (ZALF) there are experimental and fruit cultivation with substrate cultures as a dam,
(pine chips with rock flour and drip irrigation), there are attempts to continue
documents (rowan ...),
against reproduction problems.
