Soil Propertes, Nutrints availability and Wheat Productivity as affected By Compost and Nitrogen Sources

Abstract

Two field experiments were performed in Agricultural Farm of Sides Agricultural Research Station , ARC ,Beni-Suef Governorate , Egypt to investigate the effect of different levels of compost (0.0 , 4.8 and 9.5 Mg ha -1 ) and different nitrogen sources , i.e. , without ,ammonium ,sulphate (AS) , ammonium nitate (AN) and urea(U) on some soil chemical and physical properties after wheat harvested as well as wheat growth parameters ; yield and its components. The results show that all studied soil properties and nutrient availability were improved due to increasing compost level, except soil salinity, which increased by increasing compost. Also, increased compost level increased wheat growth, yields and its components as well as N, P and K content in grains and straw. N-fertilization did not affect soil properties and nutrient availability except soil reaction and soil available phosphorus. It could be arranged nitrogen sources on reducing soil pH and increasing soil available phosphorus in the descending order as follow : AS > AN > U . Irrespective of nitrogen sources, nitrogen application was significantly increased all studied growth parameters, yield and yield components and nutrients content, where as fertilizer surpassed other nitrogen forms followed by AN and U. The treatment of 9.5 Mg ha -1 compost +179 g Nha -1 consider the best treatment of wheat productivity and improved soil properties and fertility under the condition of alluvial soil for middle Egypt.

Effect of Organic Fertilizers and Foliar Application of some Stimulants on Barley Plants Under Saline Condition. تأثير الأسمدة العضوية والرش الورقي لبعض المنشطات على نباتات الشعير تحت ظروف ملحية

“…Similar results were obtained by Saison et al (2006) who reported that compost improved soil fertility and increased soil organic carbon and nutrient availability. The beneficial effect of organic manures also reported by Mohamed et al (2020) who found that compost at rate of 9.5 Mg ha -1 improved soil fertility and subsequently wheat production.…”

“…Organic manures have the possibility of providing the energy of microflora, improving soil physical, chemical and biological properties, supplying nutrients. Compost soil addition was observed to possess positive impacts that aid crop growth, therefore, improving the crop phytonutritional components (El-Hadidi et al 2020 andMohamed et al 2020). Khaled et al (2011) reported that compost possesses a vital role in saltaffected soils because the organic material causes an improving the soil properties, which have been deteriorated to the extent that passage of both air and water becomes extremely difficult in these soils.…”

Effect of Planting Dates, Compost and Foliar Spraying with some Amino Acids on Growth, Chemical Composition of feverfew (Tanacetum parthenium L.) Plants

“…The increasing application level in pots causes increasing the positive effect on soil properties, therefore, improvement of feverfew plants performance and their nutrients uptake. These results are in harmony with the obtained findings of Mohamed et al, (2020) who reported that compost caused the decline of soil pH value, thus increasing the availability of all nutrients except molybdenum element. Similar results were reported for improving plant chemical traits due to compost addition by Massoud et al, (2016) who found that chemical constituents on Yarrow plant leaves such as N P K nutrients (%), photosynthetic pigments i.e., chlorophyll a, b, total chlorophyll and carotenoids content (mg/g FW) and total carbohydrates (%) increased as the level of addition compost increased.…”

The Co-Addition of Soil Organic Amendments and Natural Bio-Stimulants Improves the Production and Defenses of the Wheat Plant Grown under the Dual stress of Salinity and Alkalinity

“…Organic manures possess the possibility of increasing soil aggregates, thus improving soil salt leach. Also it leads to provide the energy of microflora in addition to its ability to improve soil physical, chemical and biological properties and supply nutrients under salinity conditions (Al-Taey, 2017;Hafez et al, 2020;Emam et al, 2020 andMohamed et al, 2020). There are many researches with respect to the effect of organic amendments on plants grown on salt affected soil.…”
