nowadays, organic fertilizers play an important role in agriculture. they are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. they provide high yield, better quality products and a shorter period of harvesting crops. in this study, the mineral elements: primary macronutrient (n, po3- and k+), secondary macronutrient: (ca2+, mg...

Sulfur is an essential nutrient—along with nitrogen, phosphorus, and potassium—for plant growth development. mostly supplied to crops through soil fertilizers. However, chemical fertilizers are overused increase crop yields despite environmental threats. The proper use of positively affects yield increase. Regardless, residues from misuse threaten not only the ecosystem, but also marine ecosyst...

Improved crop quality and quantity is the main target of soil fertilization in conventional agriculture. However, organic agriculture, adding nutrients to threshold replenishment lost through every crop. Mineral fertilizers provide essential macro microelements plants for their active growth development. Unfortunately, these kinds easily run off from plant vicinity because frequent watering rai...

Microelements are essential for full-fledged functioning of an adult and sound growth and development of a child. Iron, iodine, folic acid, calcium etc. along with vitamins A, B1, B2, B12 and C are the most essential nutrients for our organism. Deficiency in these nutrients in a human organism is called "hidden hunger". For example, a person consumes sufficient quantities of food, but due to it...

in order to the effects of macronutrients  and micronutrients on morphological traits and yields of rice, an examination as factorial in random complete block design and 3 replicate in galoogah region during the year of 2014 conducted. the treatments of nutrients were microelements, microelements, and the mixture of microelements, macro elements and control. the results showed the treatments ha...

Algae extracts are an excellent source of chemical fertilizers (NPK) and plant growth promoters such as auxins, cytokinins, betaine, gibberellins, amino acids, macronutrients, microelements, organic matter that improve productivity. The investigation was performed at 2019-2020 through winter seasons, in sandy soil Ismailia Agricultural Research Station greenhouse. To investigate the impact nume...

abstract to study the effects of different levels of n, mn and zn on yield and quality of pomegranate fruit a factorial experiment based on complete randomized block design with 18 treatments and three replications was conducted in behshahr city, mazandaran province, in 2009.investigated treatments were include: nitrogen, manganese, zinc. fertilizer source for nitrogen was urea and three rates ...

nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...
