Influence of Compost Tea and Potassium Humate on Soil Properties and Plant Growth

Abstract

An experiment was conducted during two seasons 2018/2019 and 2019/2020, cultivated with soybean, at farm Ismailia Governorate, Egypt. The aim of this study was to evaluate the effect of two treatments (potassium humate and compost tea) at different rates of (0, 2, 4 and 6 ml/L water) with two application methods (soaking and foliar application) on soil fertility and soybean productivity. In both seasons, each experiment was carried out in randomized complete blocks design with four replicates. Data showed that the lowest value of soil pH 7.87 was obtained in the soil treated with foliar application of compost tea at 6 ml/L compared with other treatments. Also, the used of potassium Humate and compost tea foliar application was significant decrease of soil salinity (EC dSm-1), while soaking method was no significant for decrease soil salinity. The different rates of all treatments soaking method to soil gave significant increase of N and P available contents in soil while the foliar application was no significant. As well as, the K available in soil treated with all rates of treatments led to significant increase for soaking. The highest mean values of Fe, Mn and Zn contents in soil treated were with foliar application of compost tea. Compost tea soaking and foliar application increased soybean productivity. The highest values of all growth parameters plants i.e. (plant height (cm), No. of leaves/plant, No. of pods/plant, pods weight (g)/plant, seeds yield (ton/ha) and weight of 100 seed (g) were treated with potassium humate foliar application than all treatments.

“…A total of forty-six (46) The occurrence of Proteusspp, Salmonella spp, Staphylococccus spp and Bacillus spp in the soil indicates that soil is one of the biggest reservoirs of microbial diversity, yet the processes that define the community dynamics are not fully understood [21]. Similarly, Susan and Sameer [22] isolated bacterial species from the genus Bacillus, Pseudomonas, Proteus and Escherichia in their study of bacterial species in soil.…”

“…"The spread of antibiotic-resistant bacteria (ARB) is a rising problem worldwide.It has been assessed that antimicrobial resistance (AMR) is accountable for 700,000 death/year worldwide. It has also been anticipated that by 2050, AMR will be accountable for more death than cancer" [1,[46][47][48][49][50][51][52]. "Soil is a serious component of the environmental health systemand plays a vital role in human health and well-being, mainly because most food is derived from soil, that is,plants and signifies the major pathway for the transfer of essential nutrients, such as nitrogen, phosphorus and trace elements, to humans" [2,3].…”

“…The experimental design used in this trial was a randomised complete block with three replicates [45]. Each experimental plot was 5 m by 5 m square, with a 2 m buffer separating each treatment to avoid drift contamination while spraying the product.…”
