A
STUDY ABOUT THE DETERMINATION OF THE CONTENTS OF MACRO ELEMENTS (N,P,K)
AND THE
PRODUCTIVITY ABILITIES OF TEA SOILS
* Dr.
Muammer SARIMEHMET
SUMMARY
In
this study , 600 thousands decare of the tea plantations have
been
surveyed and 1678 soil samples were collected.The nutritional elements
have
been analysed in these soil samples as organic matters % , N % , P % ,
K % and
pH levels of them.
As
a result of this study ,it was determined that % of organic
matter
contents of the soils are not too low, but they are medium.It was found
that
the acidity of tea soils are too high depends on the quality and
quantity of
used nitrogen fertilizers.
It
was shown that the contents of (N,P,K) these three macro nutrient
elements are
low , and it was determined that not only nitrogen fertilizers but also
P and K
fertilizers must be used in fertilization of tea soils.
