The response of brinjal plants to organic fertilizers and inorganic fertilizers under pot experiment investigated. This invivo experiment did in the Genetics and Plant Breeding Division of the Department of Botany, University of Calicut. Brinjal plants treated with three sources of organic fertilizers (vermicompost, groundnut cake and bonemeal), three sources of inorganic fertilizers (NPK 16:16:16, NPK 10:5:20 and urea) compared with control. The experimental design followed was a Randomized Complete Block Design (RCBD) with twenty-ve replicates. Soil properties were analyzed by collecting the soil from nine representative samples from each treatment. The soil parameters such as the pH, electrical conductivity (mhos/cm), total organic carbon (%), total organic matter, total nitrogen, phosphorus (kg/ha), potassium (g/ha), manganese, sulphur, iron, zinc, copper and boron were analyzed. The results showed that the macro and micronutrient availability increased in organic fertilizer treatments. Vermicompost increased soil properties signicantly. The percentage of organic carbon increased in organic fertilizer treatments. The same result showed in the case of total organic matter. Groundnut cake treatment gave the highest organic matter (4.75). Total nitrogen was highest in bonemeal (0.95) and potassium was highest in vermicompost (330kg/ha). Phosphorous (48.33kg/ha) and sulphur (43.1mg kg-1) were recorded highest in bonemeal. The highest values of trace elements (25 mg kg-1for Fe in groundnut cake; 0.96mg kg-1Cu, 14mg kg-1 Mn, 5.1mg kg-1 Zn and 0.98 mg kg-1 B in vermicompost observed. Therefore, 38% of the increase in iron, 17.0% off copper,14.75% increase in manganese, 2.82% increase in zinc and 20.99% increase seen in boron.

Mineralizable Nitrogen

The mineralizable nitrogen pool in wetland rice soils plays a dominant role in the nitrogen nutrition of rice even in fertilized paddies. There is a lack of information on how different soil properties affect ammonification of organic nitrogen in wetland rice soils. Surface samples of 39 diverse Philippine soils representing a wide range of pH, organic matter and texture were studied to determine the relationships between ammonification of organic nitrogen and soil properties. Simple correlation analysis showed that ammonium production was correlated highly significantly with total nitrogen (r = 0.94**), organic carbon (r = 0.91**) and C/N ratio (r = -0.46**), but it was not significantly correlated with cation exchange capacity, clay or pH. Multiple regression analayses showed that organic matter (organic carbon and total nitrogen) accounted for most of the variation in mineralizable nitrogen. These results suggest that organic carbon content is a good index of mineralizable nitrogen in tropical wetland rice soils.

This research aims to evaluate some chemical parameters of surface sediments of La Restinga coastal lagoon, located in Margarita Island, Nueva Esparta State, Venezuela. Using classical methodology for geochemical studies, grain size and texture of sediment percentage of organic carbon and total organic matter, as well as calcium carbonate were analyzed. Additionally, the concentrations of total nitrogen, total phosphorus and aliphatic hydrocarbons were determined. The results showed that in La Restinga lagoon sedimentary sandy texture dominate above sandy-loam and sandy-clay. The percentages of total organic carbon, total organic matter and calcium carbonate respectively varied as follows: 1.70-25.53%, 11.10-82.10% and 2.93-44.01%. Concentrations of 282.10-1571.80 mg kg-1 in total nitrogen, 419.50-2033.70 mg kg-1 in total phosphorus and 5.65-63.18 mg kg-1 for aliphatic hydrocarbons were determined. The total organic matter in the lagoon La Restinga is distributed based on the fine particles of sediment and the presence of mangroves, in turn calcium carbonate, was associated mainly to contributions from organisms with calcareous shell. The low values of the ratio NT/PT (under 5) suggest limitation of nitrogen in the ecosystem, and natural or anthropogenic enrichment of phosphorus in the sediment. The levels found of certain aliphatic hydrocarbons, are not considered as contamination levels as established by CARIPOL (1980), except in the eastern end of the main body of the lagoon. According to the points made in this study, we can infer that La Restinga Lagoon showed symptoms of degradation product of human intervention in the ecosystem.

Millions of organic fertilizers are produced annually all over the world. Substantial quantities of these were crop residues and the remaining being animal waste based. Meanwhile maintaining and improving soil fertility in the tropic is essential for increasing food production for rapidly expanding the population. This project work, therefore, investigated the variation in soil chemical and microbiological properties as a result of yearly amendment with compost. The experimental site was the Organic Agricultural Farm located within the Federal University of Agriculture, Abeokuta. Soil samples were collected between 0 – 15 cm depth using soil auger and the samples were analyzed for the following soil parameters; total viable counts, total fungal counts, microbial biomass carbon, microbial biomass nitrogen, percentage organic carbon, microarthropod counts and earthworm counts. The experiment was a split-plot design using 2 varieties of tomato x 3 levels of compost and two durations of application. The variations include one improved variety (UCB 8) and a local variety (Beske), rate of compost – (0, 10, and 20) kg/ha and years of application (one and two years). Results generally showed that: duration has a significant effect on viable counts, microarthropod counts, microbial biomass P, microbial biomass C and percentage organic carbon but has no significant effect on fungal counts, microbial biomass nitrogen, and earthworm counts. The results indicate that application of compost manure is the preferred option to enhance SOM accumulation, improve soil fertility and quality, and increase tomato yield.

Abstract The application of inorganic fertilizers has been continuously increasing since last many decades globally. Farmers nowadays heavily rely on the use of inorganic fertilizers to meet the production of their farms and gardens. This becomes a concerning environmentally and also health issue. One solution is to decrease the use of inorganic fertilizers and substitute with organic fertilizers. In our previous work, we have developed macroalgae-based organic fertilizer (MbOF) which show promising results in increasing the growth and yield of various crops and plants. However, the quality of the formulated MbOF has never been accessed. In this study, we analysed the organic matter composition and heavy metal safety profile of the MbOF. Our results show that MbOF contains considerably high organic C (43.05 ± 2.56 %). The cumulative content of total-N (1.91 ± 0.78 %), P2O5 (2.20 ± 0.81 %) and K2O (2.18 ± 0.54 %) were also above 4%. Furthermore, the C/N ratio was sufficient (22.54 ± 5.81 %). In addition, heavy metal analyses also show low content of Pb (5.61 ± 0.71 ppm) and Hg (0.29 ± 0.14 ppm). Based on the results, the formulated MbOF could be employed as substitute or used together with inorganic fertilizer to get maximum benefits regarding yield and growth of crops and plants.

This study investigated the spatial variability of soil organic carbon (SOC), total nitrogen (TN), soil microbial biomass carbon (SMBC) and soil microbial biomass nitrogen (SMBN) in Hongqipao reservoir dominated by different vegetation types and the possible relationships with other soil properties. Top 0–50cm soil samples were collected in sites dominated by different vegetation types within the reservoir littoral zone. There was high spatial variability for SOC, TN, SMBC and SMBN in the Hongqipao reservoir. In addition, the SOC, TN, SMBC and SMBN contents decreased with increasing soil depth. This could be attributed by the fact that when plants detritus decompose, most of their organic matter is mineralized and a new soil layer which contains a greater amount of organic carbon is formed at the top. According to Pearson's correlation values and redundancy analysis (RDA) results, SOC was significantly and positively correlated with TN likely because the vegetation organic matter and liter could be the main nitrogen sources. Similarly, soil moisture content (MC) was significant positive correlated with SOC and TN. Conversely, BD was significant negative correlated with SOC and TN contents in the 0-50 cm soil profiles. However, no significant correlations were observed between SOC, TN, SMBC and SMBN contents and soil pH values. SMBN was significantly and positive correlated with C:N ratio and BD and negative related with MC. Multiple linear regression model revealed that all measures soil properties in this study could explain higher significant variability of the response variables (SOC, TN, SMBC and SMBN contents). This implies that all the measured soil variables within the different vegetation types in the reservoir played a crucial role in determining the contents of SOC, TN, SMBC and SMBN. This study further suggests that vegetation types play a major role in determining the spatial characteristics of SOC and TN. Any changes in the vegetation types in the reservoir may influence the distribution of SOC and TN. This may affect the global carbon budget and the atmospheric greenhouse gas concentration significantly.

Long-term tea cultivation has led to degradation of the soil. Old tea soils require rehabilitation for restoring soil health. Soil rehabilitation by growing different green crops can break the chain of monoculture of tea. An experiment was conducted at The Bangladesh Tea Research Institute (BTRI) Farm during 2008-2011 to find out the efficiency of different green crops on the improvement of soil properties. Four green crops such as Guatemala, Citronella, Mimosa and Calopogonium were grown to develop the nutritional value of the degraded tea soil. Soil samples were collected and analyzed before and at the end of experiment. Soil pH was increased in all four green crops treated plots with the highest increase in Citronella treated plots (from 4.1 to 4.5). Highest content of organic carbon (1.19%) and total nitrogen (0.119%) were found in Mimosa and Calopogonium treated plots, respectively. Concentration of available phosphorus, calcium and magnesium in all green crops treated plots were above the critical values, while available potassium content was above the critical value in Guatemala, Citronella and Mimosa treated plots. Changes in soil pH and available potassium were significant, while changes in organic carbon content, total nitrogen and available calcium were insignificant. Changes in available phosphorus and magnesium were significant. The Agriculturists 2014; 12(2) 34-38

The aim of the study was to compare the effect of conventional, simplified, and organic farming systems on changes in the content of soil organic carbon, organic matter fractions, total nitrogen, and the enzymatic activity. The research was conducted from 2016–2018 on arable land in the south-eastern part of Poland. The selected soils were cultivated in conventional tillage (C_Ts), simplified tillage (S_Ts), and organic farming (O_Fs) systems. The analyses were performed in soil from the soil surface layers (up to 25 cm depth) of the experimental plots. The highest mean contents of soil organic carbon, total nitrogen, and organic matter fractions were determined in soils subjected to the simplified tillage system throughout the experimental period. During the study period, organic carbon concentration on surface soil layers under simplified tillage systems was 31 and 127% higher than the soil under conventional tillage systems and organic farming systems, respectively. Also, the total nitrogen concentration in those soils was more than 40% and 120% higher than conventional tillage systems and organic farming systems, respectively. Moreover, these soils were characterised by a progressive decline in SOC and Nt resources over the study years. There was no significant effect of the analysed tillage systems on the C:N ratio. The tillage systems induced significant differences in the activity of the analysed soil enzymes, i.e., dehydrogenase (DH) and catalase (CAT). The highest DH activity throughout the experiment was recorded in the O_Fs soils, and the mean value of this parameter was in the range of 6.01–6.11 μmol TPF·kg−1·h−1. There were no significant differences in the CAT values between the variants of the experiment. The results confirm that, regardless of other treatments, such as the use of organic fertilisers, tillage has a negative impact on the content of SOC and organic matter fractions in the O_Fs system. All simplifications in tillage reducing the interference with the soil surface layer and the use of organic fertilisers contribute to improvement of soil properties and enhancement of biological activity, which helps to maintain its productivity and fertility.

The objectives of this study were to examine (1) interrelationships between various forms of extractable A1 and selected soil properties, (2) the contribution of extractable A1 to pH buffer capacity, and (3) investigate the use of extractable A1 to predict lime requirement. Aluminium was extracted from each of 60 Queensland soils with a range of chloride salts: 1 M KCl (AlK), 0.5 M CuCl2 (AlCu), 0.33 M LaCl3 (AlLa) and 0.01 M CaCl2 (AlCa). The amounts of A1 extracted were in the order AlCu > AlLa > Alk > AlCa. Little or no A1 was extracted by KC1 or Lac13 in soils with pHw values greater than 5.5 , whereas CuCl2 extracted some A1 irrespective of soil pH. The greater amounts of A1 extracted by CuCl2 were attributed mainly to A1 from organic matter, even though all of the soils were mineral soils (organic carbon 54.7%). Both AlCu and AlLa, were significantly (P < 0.001) correlated with organic carbon, whereas none of the extractable A1 measures was correlated with clay content. AlK and A~L, were poorly correlated to pH buffer capacity. The linear relationship between AlCu and pH buffer capacity (r2 = 0.49) obtained in this study supports the view of previous researchers that the hydrolysis of A1 adsorbed by organic matter is a source of pH buffering in soils. However, the change in CEC with pH accounted for 76% of the variation in pH buffer capacity, indicating that other mechanisms such as deprotonation of organic groups and variable charge minerals are also involved in pH buffering. The ability of CuCl2 and LaCl3extractable Al to estimate lime requirement depended on the target pH. The results suggest that lime requirements based on neutralization of AlLa would be sufficient to raise pHw to around 5.5, whereas requirements based on neutralization of AlCu substantially overestimated the actual lime requirement to pHw 5.5, but gave a reasonable estimation of the lime requirement to pHw 6 5.

The abundance of coconut water as a waste of household industry activities in Ponorogo can be obtained. There is still organic matter considered to become a liquid fertilizer where it can be expected to substitute for the use of inorganic fertilizers. The research aims to determine the potential of coconut water as a liquid organic fertilizer involving three types of microorganisms, such as Aspergillus niger, Pseudomonas putida and Effective Microorganisms (EM4). The experiment was conducted using a mixed bacth reactor with 4 L/ minute of aeration rate and initial microorganism`s number of approximately 107 cells/ mL for 10 days. The results suggest that the highest reduction of C-organic and the biggest enhancement of N, P, K can be achieved by a combination of A. niger and P. putida with 29 %; 100 %, 110 %, 552%, respectively.
