Abstract Background Traditional phosphorus fertilizers generally have low efficiencies due to their immobilization in soil, and a large part of these are not plant-available. Also, resources non-renewable. In recent years, great deal attention has been paid nanofertilizers because slow or controlled release also very small particle size which increases the solubility uptake nanoparticles plant....

soilless media have different physical properties. change in air space of mix substrate can cause change in fertigation management and plant growth and yield. physical properties (water holding capacity, effective air-filled pore space, effective pore space) of 50 mixed substrates were measured to evaluate the effect of air-filled pore space on growth of tomato transplant and it's water us...

Abstract This study aims to calculate the removal efficiency (%RE) of metals and sulphate constant rate reduction from acid mine drainage (AMD) based on passive treatment principles named permeable reactive barrier (PRB) in batch test prior column test. Three media mixtures containing a variety domestic sewage sludge (SE), mess hall compost (CO), cocopeat (CP), fly ash (FA) were simulated. All ...

The presence of abundant oil palm residues in Malaysia prompted the need to utilize this waste avoid environmental pollution. Palm mill effluent (POME) is a thick, brownish liquid comprising large amounts solids and high organic content, convertible into valuable source biomass. Based on nutrient content POME, has potential be utilised as an alternative plant nutrients medium different agricult...

The aim of this paper is to explain the scheme development and construction a machine that shreds coconut husks. makes use husks tender dealers have left on side road. This stack delicate causes inconvenience public. It cannot be crushed into fine powder using current shredder. A capable shredding husk has been developed. machine's 32mm shaft spins at 1200 revolutions per minute in clockwise ma...

To evaluate the physiological responses of chrysanthemum to silicon spray in non-stress conditions, this study was performed in two separate experiments (at 4 to 5 and 8 to 12-leaf stages) as a factorial randomized completely design with two factors: silicon source (in two levels: sodium silicate and calcium silicate) and the concentration of silicate at five levels (0, 50, 100, 150 and 200 mg ...
