Liming and phosphorus (P) applications are recommended practices for improving crop production in acid soils of the tropics. Although considerable work has been done to establish liming rates for acid soils in many parts of the world, information on the effects of lime on the forms of aluminium which actively sorb P in such soils is minimal. A greenhouse pot experiment was conducted at Waruhiu Farmers Training Centre, Githunguri to evaluate the effect of liming on oxalate and dithionate extractable aluminium in acid soils. Extremely (pH 4.48) and strongly (pH 4.59) acidic soils were evaluated. Four liming (CaO) rates namely 0, 2.2, 5.2 and 7.4 tonnes ha-1 for extremely acidic and 0, 1.4, 3.2, and 4.5 tonnes ha-1 for  strongly acidic soils were evaluated. The experiment was laid out in a Randomized Complete Block Design (RCBD) and replicated three times. Data collected included: initial soil chemical properties, oxalate (Alo) and dithionate (Ald) aluminium levels. The tested soils had high exchangeable Al (> 2 cmol Al kg-1), Al saturation of (> 20% Al) and low extractable P values (< 15 mg P kg-1 soil). Liming significantly (p=.05) reduced Alo by 70% and 68% in extremely and strongly acidic soils respectively and Ald by 78% in both extremely and strongly acidic soils compared to control. Use of 7.4 tonnes ha-1 of lime in extremely acidic soils and 4.5 tonnes ha-1 of lime in strongly acidic soils significantly (p=.05) reduced both Alo and Ald by > 68% compared to no lime. It was, therefore, concluded that liming contributes to the reduction of soluble Alo and Ald in acid soils of the Kenya highlands leading to increased soluble P availability. Studies are required to provide short and long term optimal liming rates that reduce Alo and Ald without distabilizing availability of other nutrients in field conditions under wide range of acid soils.

Low soil organic matter, low nutrient availability and the higher soil pH (more than 8) are the major problem of agricultural practices in region of Toshka. An incubation trial at October 2019 was conducted to investigate the effect of potassium humate (KH) and micronic sulfur (MS) on some chemical properties of different soils (sandy clay soils, loamy sand and sandy soils). The used amendments (KH and MS) were added to the studied soil at 4 levels of each amendment i.e. 0.0, 0.25, 0.50 and 1.0%. A two way randomized completely block design and provided with three replications. Studied parameters were included soil pH, EC, exchange Na and the content of available - P and K. Results showed that, the MS application at 1% level caused a significant decrease in soil pH values compared with the KH application and control treatment. These reductions were more pronounced in case of soil B (loamy sand). Also, KH application gave an increase on exchange Na and available-K. While MS application was cause an increased in soil EC and available-P in the three soils under study. Moreover, the increases in the percentage of available – K with added of KH were higher than added of MS for soils under study. While the percentages of available-P with added of KH were higher than with added of MS for studied soils. It may be recommended to add KH and MS at a rate of 1% to improve the soil chemical properties. But the effect of application from MS has greater than KH to increase dissolved sodium salts on the form of sodium sulfate, which facilitates disposal during soil drainage.

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.

Application of animal manures for soil amendment plays a major role in the improvement of soil properties and enzymatic activities of a degraded Ultisol. This study assessed the effects of poultry manure (PM) and swine manure (SM) on the activities of catalase and urease enzymes and some soil properties. The PM and SM were applied at the rate of 30 t ha–1 each on experimental plots arranged in a randomized complete block design with three replicates. Soil samples were collected at day 0, 14, 28, 42, 56, 70 and 84 from 0-15 and 15-30 cm depths and analyzed for catalase and urease enzymes and some soil properties using standard procedures. The results showed increase in soil pH (in H2O) from 4.0 to 5.4 following manure application. At 0-15 cm soil depth, PM and SM recorded 28.1 and 28.8% increases in soil pH (in H2O), respectively. Soil organic carbon was highest (2.6 g kg–1) at 0-15 cm depth for soil amended with SM while the lowest value of 1.1 g kg–1was obtained at 15-30 cm depth for soil unamended with SM. In PM-amended soil, catalase activities ranged from 1.32 to 6.77 mg g–1 while its activities in SM-treated soil significantly (p < 0.05) varied between 1.55 and 8.11 mg g–1. Urease showed ranges of 0.72-3.90 mg g–1 and 0.96-4.71 mg g–1 in PM-amended and SM-treated soils, respectively. The results uphold that animal manures improve soil properties and are enzymatically controlled.

Membrane Bio Reactor(MBR) methods is considered as one of the most advanced used technology in waste water treatment. The aim of this technology is to obtain high quality treated waste water. This study conducted to investigate the ability of using of sewage water from zaafrania city for irrigation and their effect on corn growth and some of soil chemical properties which include electrical conductivity and soil pH in extract soil paste and the micro nutrient content in soil and plant which include Fe, Mn, Zn, Cu, Cd, Pb. Three levels of wastewater were used 0, 50, 100% in two stages, the three levels of wastewater ( without soil fertilization ) were used in the first stage, where 21.8 Kg P/D +80 N Kg/D was added to the soil as fertilizer in the control 0% treatment and 10.9Kg P/D +40 Kg N/D were added to 50 and 100% levels in the second stage. Corn seeds were planted in 10kg plastic pots in Completely Randomized Block Design in three replicates. The results refer to a high significant increase in plant height, fresh and dry weight for all treatments in comparison with control treatment. The low add level of wastewater 50%+ half of fertilizer recommendation gives a significant increase of plant height and fresh and dray weight. The results showed a high increased of electrical conductivity for 50, 100% wastewater added levels for both stages compared with control treatment. The high add level 100% gives high significant increase of electrical conductivity compared with the low level of the wastewater. Whereas the values of soil PH were close to the neutral for all treatment. The result showed a significant increase in micro nutrients content (which include Fe, Mn, Zn, Cu, Cd, Pb) in soil and plant for all treatment compared with control treatment, this increased was continues with the increase of additional level of wastewater. However all the micro nutrient was within the allowed natural limits and not reached the toxic limits in soil and plant.

A field trial was conducted to evaluate the application of four soil amendments: sand, gypsum, cow manure and granular sulfur to improve the soil conditions under center pivot irrigation system to manage the mechanization of potato crop harvest in the autumn of 2012; the application of sand amendment was to facilitate mechanical harvest. Evaluation on the improvement of the soil properties were carried out during the growing season through monitoring the changes on soil texture and structure, saturation percentage, bulk density, soil pH and soil salinity. Clods formation occurred at all of the treatments at the harvest time an indication of negative structure improvement due to field trafficking for soil ridging, and spraying during the growing season. The clods samples contained higher %calcium carbonate and higher level of % (Silt+Clay) and less %sand than normal soil samples. Bulk density in the sand treatment was 1.41 gram/cm3 which was significantly higher than the other treatments which ranged 1.13 - 1.19 gram/cm3. Saturation percentage increased at all of the treatments over the period of the experiment from 21 to 31 an indication of significant improvement on the soil water holding capacity. Salinity as measured by the soil Ec was significantly increased over the period of the experiment due to fertilizer application, and salinity at the cow manure treatment was higher than other treatments due to high salt level in the cow manure which reached an Ec average of 5.57 mS/cm over the period of the experiment. Chloride and bicarbonate levels were high and increased on all of the treatments at most sampling occasions of the trial, and sodium level was within the acceptable level.

Sandy soil has limitations factor in supporting plant growth such as low soil organic carbon (SOC), cation exchange capacity (CEC), macro-micro nutrient content, water retention capacity, and high permeability rate. To improve soil conditions, it can be done by adding mycorrhizae and soil amendments. This study aimed to determine the effect of mycorrhizae application and soil amendments on the P availability and P uptake of plants in sandy soil. The research was conducted in a greenhouse of Agricultural Faculty, Sebelas Maret University. Used a completely randomized design consisting of 2 factors. The first factor was mycorrhizae with 2 levels, namely without mycorrhizae (M0) and mycorrhizae with 6 spores/plants (M1). The second factor was soil amendments; without amendment (P0), cow manure 60 tons/ha (P1), rock phosphate 150 kg/ha (P2), and combination of cow manure 60 tons/ha and rock phosphate 150 kg/ha (P3). The results showed that the application of mycorrhizae and soil amendments significantly increased available P, SOC, CEC, P concentration, and P uptake. Interaction of mycorrhizae 6 spores/plant and rock phosphate 150 kg/ha was able to increase the availability of soil P up to 12.8 times, plant tissue P concentration up to 1.4 times, and P uptake up to 2.27 times compared to the control. Application of mycorrhizae 6 spores/plant and cow manure of 60 tons/ha gave the best results on SOC and mycorrhizae with a combination of cow manure and rock phosphate gave the best results on CEC.
