Subject(s): Online resources: In: Minufiya Journal of Agricultural Research 2015.v.40(3)P.2Summary: In order to appraise the role of organic manures in improving soil properties, a field experiment was conducted at the Experimental Farm of Sakha Agriculture Research Station, Kafr El- Shikh, Egypt to study the effect of compost as (4 or 8 ton fed-1) along with Potassium- Humate (K-H) and fulvic acid (F A) as (20 L fecd-1) on some physical properties of the studied soil. The treatments comprised Qf 1) control (soil treated with 100 % NPK of recommended doses 2, 3) soil treated with either K -H or F A as 20 L fed-1 4, 5) soil treated with compost at the rate either 4 or 8 ton fed-1 6, 7) compost combination (4 and 8 ton fed-1) by K-H as (20 L fed- 1 ) respectively 8, 9) compost combination (either 4 or 8 ton fed-1 ) by fulvic acid as( 20 L fed-1). The wheat crop (Triticum aestivum L., var Sakha 93) was selected as concerned crop. The obtained results indicated an improvement in soil physical properties as affected by soil conditioners wherever those application slightly decreased soil bulk density and total porosity values compared to control (100% NPK) , improved soil aggregation as dry and wet stable aggregates along with structure parameters i.e., aggregate state (A. S), aggregate degree (A.D) , aggregate index (A.I) and ? M.W.D. As well as soil hydraulic conductivity (HC) and moisture content at both field capacity and available water were increased compared to the control (100 % NPK) c) . The combined treatments of compost with K-H or FA had superior effect compared to other treatments in improving physical properties of the studied soil. Key words: Compost, K- humate, fulvic acid, soil physical properties.
