The aim of the study was to assess and evaluate the effect of soil conditioner on the
spatial variability of soil environment. Activator PRP-SOL conditioning soil properties was
selected as a field of study. Assessment of soil environment was done through the evaluation of
selected soil properties, namely, tensile resistance of the soil and soil infiltration ability. Two
dose of PRP-SOL application was done twice in year 2015 (Autumn and Spring) and once in
2016 (Spring) with application rates 150 kg ha-1
and 140 kg ha-1
, respectively. The area was
divided into blocks where stimulators were applied and none treated as a control. The evaluation
of recorded values showed that treatability and tillage itself was significantly better on the area
which was treated by application of PRP-SOL activators. In addition, tensile resistance was
decreased by 5.71% in comparison with non-treated area of experimental field. Since the
infiltration ability is among the very important soil properties which have an effect on soil
moisture regime as well as surface runoff and therefore soil erosion. The evaluation of recorded
values has revealed the effect of treatment by PRP-SOL activators on soil infiltration ability and
therefore it results in increases infiltration of precipitation as well. Overall increase of infiltration
was recorded at value 2 mm h
-1
. It can be concluded that application of soil activators may
increase the soil conditions and therefore not only conserve soil fertility but even increase it from
the long term perspective.
