Abstract
The popularity of using the Inorganic and organic soil amendments is based on the current status
of soil degradation that led to decline in fertility of soils, resulting to low yields. The objective of
current study was to evalute different organic and inorganic soil amendments and their effects on
soil pH and macronutrients. The study was laid out as randomized complete block design (RCBD)
in split plot arrangement for two seasons. The treatments were ChalimTM, Super-hydro-grow
polymer + Metham sodium, Metham sodium, Metham sodium & Orange peel, Super-hydro-grow
polymer, Brassica tissues, ChalimTM + Super-hydro-grow polymer, Brassica tissue + Orange peel,
Metham sodium + Super-hydro-grow polymer and Control (no amendments). Soils were sampled
from each experimental site, dried and taken to laboratories for determination of soil chemical
properties both at initial and at the end of the experiment. The soil physicochemical attributes
assessed included: Soil pH, nitrogen, carbon, phosphorus, potassium and calcium. There was an
significant increase (P≤0.05) in the concentration and availability of soil physicochemical
characteristics after treatment which is an indicator of improved soil structure. Brassicae tissue +super hydrogrow polymer (BT+SHG) amendment was the best as it resulted to highest
concentration and availability of the mineral elements in the soil recording total nitrogen of 0.50 %,
organic carbon 5.47 %, phosphorus 19.7 mg/kg, and potassium 1.37 %. The control exhibited the
least impact on all the soil chemical properties. We recommend BT+SHG amendment to farmers to
promote soil fertility which will consequently produce better yield.
