This paper studied the maize tolerance under salinine water (ECw) and their relationship with the changes of soil chemistry characteristics, crop growth and yield of maize. The seven level of water salinity were 0.66, 0.93, 1.57, 1.68, 2.46, 3.35, 3.85 mS cm-1 and three local maize from Madura, Pasuruan and Probolinggo were evaluated to soil electric conductivity (ECe), pH, available -N. -P. and -K as well as plant height and seed weight The experiment indicated that saline water (ECw) up to a certain concentration increased soil salinity (ECe) and pH, but decreased nutrient availability, plant height, fresh and dry weight of maizes. ECw level between 1.5 to 1.7 mS cm-1 gave the best results compared to others, because of soil nutrients and water availability optimum. Maize of Madura and Pasuruan were more tolerant than Probolinggo giving ECw up to 3. 85 mS cm-1, although their maize seed dry weight were lower.

On the other hand, the dynamics of saline soil cation is strongly influenced by the change of seasons that disrupt water and plant nutrients uptake. This experiment was aimed to examine the characteristics of the humic acid from compost, coal, and peat and its function in the adsorption of K + and NH 4 + cations, thus increasing the availability of nutrients and of maize growth. Eighteen treatments consisted of three humic acid sources (compost, peat and coal), two cation additives (K + and NH4 +), and three doses of humic acid-based buffer (10, 20, and 30 g / 3kg), were arranged in a factorial completely randomized with three replicates. The treatments were evaluated against changes in pH, electric conductivity (EC), cation exchange capacity (CEC), chlorophyll content, plant dry weight and plant height. The results showed that the addition of K + and NH4 + affected pH, CEC, K + , NH4 + , and water content of the buffer. Application of humic acid-based buffer significantly decreased soil pH from > 7 to about 6.3, decreased soil EC to 0.9 mS / cm, and increased exchangeable Na from 0.40 to 0.56 me / 100g soil, Ca from 15.57 to 20.21 me/100 g soil, Mg from 1.76 to 6.52 me/100 g soil, and K from 0.05-0.51 me / 100g soil. Plant growth (plant height, chlorophyll content, leaf area, and stem weight) at 35 days after planting increased with increasing dose of humic acid. The dose of 2.0g peat humic acid + NH 4 + / 3 kg of soil or 30g peat humic acid + K + / 3 kg of oil gave the best results of maize growth.

A treatment of humic acid of 50-90 mg /L on a farmland has been able to reduce illness and death compared to a mixture of formaldehyde and blue-green methylene. Humic acid is suspected to be able to increase yield, through improved conditions and resistance to diseases, health, and cultural vitality, either by itself or combined with cation species toxic. Humic acid can balance the soil cation so that the soil pH reached 7-8, through a chelate of Al, Fe, Ca or exchanged with NH4, Na and K. Humic acids were extracted from compost plants with a weak base of 0.1 N NaOH and precipitated at pH 2. The concentration of AH 0-400 ml was applied to three soil types with an area of 0.12 m 2 and 15 cm thickness. The results showed that the application of 100-200 ml HA/0.12 m 2 gave optimum yield in improving the physical-chemical characteristics of the soil embankment. Soil pH reached a value of 7-8, cation exchange to 60% saturated, and soil bulk density was reached in the range of 1.1-0.97 g / cm 3 .This condition is suitable for fish or shrimp in the embankment.

The purpose of the study was to assess the characteristics of the land in the area of sample plant, soil capability, soil fertility and land suitability and its relationship to the production of biomass for rice (Oryza sativa ) . The study was done in farmers fields at Wringinpitu dan Catak Gayam village, Mojowarno Subdistrict, Regency of Jombang and at Land Resources Laboratory, the Faculty of Agriculture, UPN " Veteran " East Java from March 2013 to June 20013 . pH value of the soil in the study site is generally near neutral. Low C and N content of below 1 % , but the available of P content is high. The low content of C-organic due to the amount of biomass that is transported ou t of the good land for cattle feed, or burned for the sugar production. Low soil N content due to easy N-ammonium content evaporates when exposed ...

The high water content of Vertisol causes the air to decrease, thus inhibiting root development. Stretching of the Vertisol structure is expected to increase soil porosity and reduce ion and water absorption. This study examines interactions between organic matter and percent sand on soil porosity and nutrient availability. The study was arranged according to a factorial Completely Randomized Design (CRD), repeated three times. The first factor was seven kinds of organic matter (control, cow dung + banana peel compost, cow dung + leaf litter compost + compost water hyacinth + cow dung, humin, humic acid, and biochar. The application doses are respectively for each treatment: humic acid and humin 20 kg ha-1, biochar 1 Mg ha-1, compost+manure fertilizer 15 Mg ha-1. Changes in soil chemical characteristics were evaluated against pH, C-org, and Available-P, while changes in soil physical charac...

High concentration of dissolved salt decreases growth and rice yield. The study aimed to evaluate physical and chemical characteristics of saline soil in Sidoarjo and Surabaya, East Java, Indonesia. The result analysis of soil exchangeable Na + , K + , Ca ++ , and Mg ++ respectively was 0.8-1.94; 0.33-2.73; 16.32-20.4, 1.83-8.88 me.100g-1 .The value of soil pH was 7.35-7.55, EC value of soil was 0.64-1.83dS.m-1 , and the content of organic-C was between 1.1-2,4,6 %. The result of soil characterization was then crosschecked with the rice yield in saline soil by weighing dry rice grains per clump. The rice yield was 3-4.1 ton.ha-1 and negatively correlated to the exchangeable values of Na, SAR, bulk density and dust content. It was positively correlated with organic-C, fertilizer, exchangeableof Ca ++ , Mg ++ , and K + , as well as soil's CEC. The ratio value of Ca:Mgnamely2.2-8.2, and K:Mgnamely0.18-0.21 exceeded the limit of ideal value and caused low production. The rice yield was negatively correlated with the content of exchangeableNa + , values of pH and EC. It achieved more than 4 ton.ha-1 when added with 300-450 g.plant-1 of organic materials and 1.0-1.3 g.plant-1 of NPK.

This condition is caused by the soil matrix which has no negative charge, so that nutrients are easily lost due to washing. Nitrogen loss has been reported to reduce rice production by 6.10%. The research aims to examine the application of humic acid and silica to increase the availability of nitrogen nutrients. Humic acid from compost and silica from rice husk is expected to increase the negative charge of the soil so that can adsorbnutrient ions such as nitrogen. The research was carried out from March to September 2021 in the greenhouse and laboratory of the Faculty of Agriculture, National Development University "Veteran" East Java. The research was structured using a factorial Completely Randomized Design (CRD). The first factor is silica dose with a level of 0 ton/ha, 0.5 ton/ha, 1 ton/ha, and 1.5 ton/ha. The second factor is the dose of humic acid with a level of 0 kg/ha, 20 kg/ha, 40 kg/ha, and 60 kg/h...

This research aimed to assess the availability of P and Zn, the best growth, and yield of tomato plants using liquid organic fertilizer based on animal manure. A completely randomized design with a two-factor treatment was used to set up this study. The first aspect is the three different kinds of organic livestock-based fertilizers—chicken, goat, and cow dung. The second factor is the three different fertilizer concentrations, which are 5 ml/g (1), 10 ml/g (2), and 15 ml/g (3). A control was added as a point of comparison, and each treatment was performed three times overall for a total of 30 experimental units. After 7 days have elapsed after planting, liquid organic fertilizer is applied. The following parameters were measured: plant height, number of fruits, fruit weight, fruit sugar content, soil pH, soil accessible P, and total soil Zn. According to t...

A survey method was employed in this investigation. The findings of the chemical characteristics test were utilized as a guide for creating maps of the land fertility potential for coffee plants in Tutur Village. These maps included information on water content, soil pH, C-Organic content, N-total content, Phosphorus content, base saturation, and CEC. According to this study, Tutur District's coffee farming may be classified into three soil fertility status categories: low, medium, and high fertility status. The slope of the land is the factor that has the biggest impact on the soil fertility in the Tutur District's coffee growing region; the steeper the slope, the less fertile the soil is.
