Adoption of new management techniques that improve soil water storage and soil N plant availability yet limit N leaching may help improve environmental quality. A benchtop study was conducted to determine the influence of a single urea fertilizer rate (224 kg N ha) applied with band or fully mixed zeolite (clinoptilolite) application rates (up to 90 Mg ha) on NH4-N and NO3-N concentrations in a...

greenhouse experiment was conducted to assess the response of wheat to tank mixture of herbicides with insecticide and manure in ferdowsi university of mashhad, iran. the experiment consisted of 8 treatments: 1- tribenuron methyl (15-20 g ha-1) + clodinafop propargyl (0.8 l ha-1) 2- tribenuron methyl + clodinafop propargyl + fenitrotion (1.2 l ha-1) + librel (1 kg ha-1) 3- tribenuron methyl + c...

Abstract The objective of this work was to evaluate the losses N-NH3 by volatilization and agronomic efficiency a mixture urea with natural zeolite, as topdressing fertilization, in an area for commercial production roses (Rosa spp.). treatments were: two rates (60 120 kg ha-1), without zeolite. N sources were applied directly soil surface, determined using free semi-open static chamber. quanti...

Soil fertility degradation remains the major biophysical cause of declining per capita crop production on smallholder farms in sub-Saharan Africa. Appropriate soil fertility regimes, are therefore, critical for improved crop productivity. This study investigated the feasibility of using sole organics or their combinations with inorganic fertilisers to improve maize (Zea mays) production in the ...

The paper presents the results of studies on effectiveness zeolite, including enriched with amino acids, in cultivation millet. study was carried out experimental field Ulyanovsk State Agrarian University 2019 by following scheme: 1. Control, 2. Zeolite 500 kg/ha, 3. kg/ha. In 2020, options were introduced into scheme. 250 4. kg/ha 5. soil typical medium loamy chernozem. and zeolite fertilizers...

Humic acid (HA) can supplement the chemical fertilizers to reduce the input cost of agricultural production. Field experiments on increasing cotton [Gossipium hirsutum L, cv. CIM-473] crop yield through HA were conducted in salt-affected soil of Kohat division, NWFP, Pakistan, during Kharif 2005 at two sites being irrigated with tube-well saline waters. Four levels of humic acid (0, 0.5, 1.0 an...
