. LI Sheng-nan 2015-12-01 Full Text Available The effect of two Se-enriched organic fertilizers (cow dung and rice straw biochar on selenium accumulation of corn growing in selenium deficient soil was studied with pot experiment.
The results showed that corn accumulated more selenium and the selenium was much easier to convert from root to shoot in the corn plant with the application of Se-enriched cow dung than Se-enriched rice straw biochar. With the application of more organic fertilizer such as 25 thm-2 Se-enriched cow dung or 40 thm-2 Se-enriched rice straw biochar, the accumulation of selenium and growth status of corn were getting better than the other treatments. At the same time, as the application amount of Se-enriched organic fertilizers (cow dung and rice straw biochar increased, the total selenium content in the soil also increased, which positively correlated with each other. Kojuhov 2012-07-01 Full Text Available The use of fertilizers in cultivation of crops is an objective necessity. However, their use has a negative impact on environment and especially on the soil polluting it with heavy metals. Organic fertilizers can significantly improve physical and chemical soil properties and increase its fertility.

In connection with deficiency of manure particular interest represents using of waste as non-conventional fertilizers, in particular waste of alcohol production. Using of high-dose alcohol stillage stronger growth processes and number of leaves, which leads to an increase of maize photosynthetic activity and productivity. Maximum formation of green mass was observed in variant with a dose of making alcohol stillage 40 m3/ha during vegetation.

Djajadi Djajadi 2017-02-01 Full Text Available Sugarcane is known to absorb more Si than any other nutrient from the soil; therefore continuous cropping of the plant at the same soil would bring consequences of more Si and organic matter depletion. Silicon (Si is considered as a beneficial nutrient for sugarcane production while organic matter is well known as soil amendment.
Field study was carried out to know the effect of organic and Si liquid fertilizer on growth, Si and N uptake, and yield of cane variety of PSBM 901. The study field was located at Kempleng village, Purwoasri, East Java and the study was done from May 2013 up to September 2014. Split plot design with three replicates was employed to arrange treatments. Organic matter types (no organic matter, Crotalaria juncea and manure were set as main plots while Si liquid fertilizer concentration (0, 15% Si and 30% S were arranged as sub plots. C juncea was planted at 15 days before planting of sugar cane, and after 35 days the C juncea were chopped and mixed into the soil. Manure was added one week before sugar cane was planted.
Si liquid fertilizer was sprayed to the whole part of sugar cane plant at 30 and 50 days after sugar cane was planted. All treatments received basal fertilizer of 800 kg ZA/ha, 200 kg SP 36/ha and 300 kg KCl/ha. Results showed that interaction between organic matter and Si liquid fertilizer significantly affected on Si and N absorption, length of stem, yield and rendement of sugar cane. Addition of manure and followed by spraying of 30% Si liquid fertilizer gave the highest value of S and N absorption (869 g SiO2/plant and 720 g N/plant, cane yield (155.74 tons/ha and rendement (8.15%. Piadang, Nattayana; Palajoom, Somsak; Kumklang, Tawan; Laothamyingyong, Metinee; Sirodomsakul, Pranee 2006-09-01 The study was conducted to determine the yield of baby corn production treated with wastewater from swine farm. The experiment was set up following the Randomized Complete Block Design with 7 treatments 4 replications. The treatments were no fertilizer, chemical fertilizer, compost, liquid microbial fertilizers (LMF.) of OAP, liquid fish fertilizer (LFF.) of NM., wastewater from swine farm with biogas (SFbg.) and wastewater from swine farm without biogas (SF.).
Results at harvested stage of test pot experiment revealed that plant height of liquid fish fertilizer (LFF.) except chemical fertilizer (P.
