Group Empowerment

Boyolali district is one of the areas that has decreased productivity of rice. The decline was due to acidic soil conditions coupled with a lack of awareness of farmers and lack of support for facilities and infrastructure. Basically, to find out the conditions of the soil can be done by detecting the soil using a pH meter. The tool is not widely used because the price is expensive and the farmers care less about the conditions of their paddy fields. The aim of this program is to empower the farming group to be the agent of land rehabilitation through early detection of CurcuMarvel using tumeric. Soil detection devices can be innovated using turmeric. Turmeric that is easily found and familiar among farmers is the solution to the problem of detecting soil conditions. The target was Sari Tani Farming Group located in Suyudan Village , Boyolali Regency. The program involved 10 farmers as the representative of the farmer group. Empowerment programs were conducted by combining several methods, including participatory, discourse, demonstration, and discussion. The activities of CurcuMarvel consist of: (1) transferring information using educational video; (2) demonstrating the soil acidity detection in one of the farmer's paddy fields; (3) land rehabilitation efforts by applying dolomite, manure, and biological fertilizer in the demonstration plot; and (4) turmeric cultivation training in the farmer's yard to prepare the village as the turmeric cultivation center. The outcomes of the program are: (1) the farmers know that their paddy land is acid; (2) the farmers increase their awareness towards the soil acidity effect; (3) the farmers conduct soil rehabilitation; and (4) the farmers have a turmeric center near to the paddy field.

Subsurface drainage technology may offer a useful option in improving crop productivity by preventing water-logging in poor drainage paddy fields. The present study compared two paddy fields with and without sheet-pipe type subsurface drainage on land and water productivities in Indonesia. Sheet-pipe typed is perforated plastic sheets with a hole diameter of 2 mm and made from high-density polyethylene. It is commonly installed 30–50 cm below the soil surface and placed horizontally by a machine called a mole drainer, and then the sheets will automatically be a capillary pipe. Two fields were prepared, i.e., the sheet-pipe typed field (SP field) and the non-sheet-pipe typed field (NSP field) with three rice varieties (Situ Bagendit, Inpari 6 Jete, and Inpari 43 Agritan). In both fields, weather parameters and water depth were measured by the automatic weather stations, soil moisture sensors and water level sensors. During one season, the SP field drained approximately 45% more water compared to the NSP field. Thus, it caused increasing in soil aeration and producing a more significant grain yield, particularly for Inpari 43 Agritan. The SP field produced a 5.77 ton/ha grain yield, while the NSP field was 5.09 ton/ha. By producing more grain yield, the SP field was more effective in water use as represented by higher water productivity by 20%. The results indicated that the sheet-pipe type system developed better soil aeration that provides better soil conditions for rice.

Paddy fields, which are shallow man-made wetlands, are estimated to be responsible for ~11% of the total methane emissions attributed to anthropogenic sources. The role of water use in driving these emissions, and the apportioning of the emissions to individual countries engaged in paddy cultivation, are aspects that have been mired in controversy and disagreement. This is largely due to the fact that methane (CH4) emissions not only change with the cultivar type but also regions, climate, soil type, soil conditions, manner of irrigation, type and quantity of fertilizer added—to name a few. The factors which can influence these aspects also encompass a wide range, and have origins in causes which can be physical, chemical, biological, and combinations of these. Exceedingly complex feedback mechanisms, exerting different magnitudes and types of influences on CH4 emissions under different conditions, are operative. Similar is the case of nitrous oxide (N2O); indeed, the present level of understanding of the factors which influence the quantum of its emission is still more patchy. This makes it difficult to even understand precisely the role of the myriad factors, less so model them. The challenge is made even more daunting by the fact that accurate and precise data on most of these aspects is lacking. This makes it nearly impossible to develop analytical models linking causes with effects vis a vis CH4 and N2O emissions from paddy fields. For situations like this the bioinspired artificial intelligence technique of artificial neural network (ANN), which can model a phenomenon on the basis of past data and without the explicit understanding of the mechanism phenomena, may prove useful. However, no such model for CH4 or N2O has been developed so far. Hence the present work was undertaken. It describes ANN-based models developed by us to predict CH4 and N2O emissions using soil characteristics, fertilizer inputs, and rice cultivar yield as inputs. Upon testing the predictive ability of the models with sets of data not used in model development, it was seen that there was excellent agreement between model forecasts and experimental findings, leading to correlations coefficients of 0.991 and 0.96, and root mean square error (RMSE) of 11.17 and 261.3, respectively, for CH4 and N2O emissions. Thus, the models can be used to estimate CH4 and N2O emissions from all those continuously flooded paddy wetlands for which data on total organic carbon, soil electrical conductivity, applied nitrogen, phosphorous and potassium, NPK, and grain yield is available.

Soil acidity and aluminum toxicity are considered most damaging soil conditions affecting the growth of most crops. This paper reviews the results of tests of pH, exchangeable acidity and mobile aluminum (Al) concentration in profiles of pseudogley soils from Cacak-Kraljevo basin. For that purpose, 102 soil pits were dug in 2009 in several sites around Cacak- Kraljevo basin. The tests encompassed 54 field, 28 meadow, and 20 forest soil samples. Samples of soil in the disturbed state were taken from the Ah and Eg horizons (102 samples), from the B1tg horizon in 39 field, 24 meadow and 15 forest pits (a total of 78 samples) and from the B2tg horizon in 14 field, 11 meadow, and 4 forest pits (a total of 29 samples). Mean pH values (1M KCl) of the tested soil profiles were 4.28, 3.90 and 3.80 for the Ah, Eg and B1tg horizons, respectively. Soil pH of forest samples was lower than those in meadow and arable land samples (mean values of 4.06, 3.97 and 3.85 for arable land, meadow and forest samples, respectively). Soil acidification was especially intensive in deep horizons, as 27% (Ah), 77% (Eg) and 87% (B1tg) soil samples had the pH value below 4.0. Mean values of total exchangeable acidity (TEA) were 1.55, 2.33 and 3.40 meq 100 g-1 for the Ah, Eg and B1tg horizons, respectively. The TEA values in forest soils were considerably higher (3.39 meq 100 g-1) than those in arable soils and meadow soils (1.96 and 1.93, respectively). Mean mobile Al contents of tested soil samples were 11.02, 19.58 and 28.33 mg Al 100 g-1 for the Ah, Eg and B1tg horizons, respectively. According to the pH and TEA values, mobile Al was considerably higher in the forest soils (the mean value of 26.08 mg Al 100 g-1) than in the arable soils and meadow soils (the mean values of 16.85 and 16.00 mg Al 100 g-1, respectively). The Eg and B1tg horizons of the forest soil had especially high mobile Al contents (the mean values of 28.50 and 32.95 mg Al 100 g-1, respectively). High levels of mobile Al were especially frequent in the forest soils, with 35% (Ah), 85.0% (Eg) and 93.3% (B1tg) of the tested samples ranging above 10 mg Al 100 g-1.

In southern Veracruz, Mexico, soil acidity is one of the main environmental factors that reduce the production yield of common bean. The objectives of this research were to identify outstanding opaque black bean breeding lines according to their level of adaptation to acid soils and high yield eff iciency with and without the addition of dolomite into the soil, as well as to determine which is the yield component that associates the most to a greater production of beans. During the Fall/Winter season of 2016-17 two trials were performed in Juan Rodríguez Clara, Veracruz, in a land with a soil of initial pH = 4.67. One trial was conducted under stress conditions by soil acidity and the other with 2.58 Mg ha-1 of dolomite, applied to the soil 27 d before sowing. Twelve black bean breeding lines were evaluated and compared to Negro Grijalva and Negro Comapa bean varieties. All beans were arranged in a randomized complete block design with three replicates. The variables measured were dry matter production without grain, weight of 100 seeds, number of pods per plant and grain yield. An analysis of variance of the quantif ied variables and the least signif icant difference (LSD, 0.05) tests for separation of means were performed. Negro Citlali/XRAV-187-3-1-8 showed the best adaptation to acid soil conditions in southern Veracruz, which obtained yields of 911.0 and 706.3 kg ha-1 with and without dolomite, respectively. These values were signif icantly higher than the commercial beans. This breeding line also showed the highest productive eff iciency, since it obtained the highest geometric mean (MGi) values (802.1) and a relative eff iciency index (IERi) of 2.00. Under both conditions of edaphic acidity, the number of pods per plant was the only plant trait that was positively related to seed yield (r = 0.91 ** and 0.87 **, with and without dolomite).

SUMMARYMost acid sulphate soils (ASSs) in the Pearl River Delta of South China have been traditionally reclaimed for rice cultivation, but the rice yield in most of these paddy fields is lower than the average rice yield in China due to extremely high soil acidity. In the present study, a range of sulphate and acidity parameters were investigated in ASS profiles in three types of paddy fields in Taishan City (Guangdong Province, China) divided based on the local rice productivity (4500, 3000 and 1500 kg/ha) using an abandoned ASS (uncultivated) as the control treatment to ascertain key yield constraining parameters. Soluble acidity (SA), exchangeable acidity (ExA), soluble sulphate (SS) and net acid-soluble sulphate (NAS) increased with increasing soil depths from 0 to 100 cm and then decreased abruptly with further increases in the depth. However, the depth distribution of exchangeable sulphate (ES) was uniform. The soil acidity and sulphate contents differed significantly in three sampled paddy fields. The values of SA and SS in the soils at depths of 0–100 cm in the studied ASS were lower compared with those in the uncultivated ASS and the ExA in soils at depths of 0–40 cm in ASS were lower compared with those observed in the uncultivated ASS. A correlation analysis revealed that SA was strongly correlated with SS and ExA with NAS. Soluble acidity, ExA, SS and NAS in the ASS were significantly associated with rice yield. Exchangeable acidity in the plough layer (0–20 cm) of soils was the most sensitive indicator of soil quality affecting rice yield among those in soils from 0 to 140 cm depth. It is interesting to note that SA, SS and NAS were more sensitive indicators of soil quality affecting rice yield at 60–100 cm than at 0–40 cm depth. Principal component analysis showed that pH value, ExA and ES in soils at depths of 0–40 cm and SA, SS and NAS in soils at depths of 60–100 cm constituted the critical soil acidity and sulphate characteristics that were strongly correlated with rice yields. This finding implies that controlling the ExA in the plough layer and the SA and NAS in the Jarosite layer should be the major focus of studies aimed at the amelioration of ASSs.

Land resources are part of nature related to the availability of water, nutrients, and food that are dynamic and play an important role in the lives of living creatures, including humans. From time to time, land use experiences changes in response to human activities that benefit their lives. This research was conducted to determine trends in land use change in North Maluku Province, Indonesia, as well as to find out the land resource balance and land carrying capacity in the province. The methods comprised a simple descriptive and quantitative analysis along with spatial analysis using GIS. The results showed that land use in North Maluku Province for paddy fields was higher than that for non-paddy land use. However, the increase in non-paddy land use was greater every year compared with the increase in paddy land use. The land resource balance in North Maluku Province in 2010–2018 also showed a decrease in non-agricultural protected forest, by 150,895.79 ha, as well as an increase in 4,286 ha of irrigated paddy fields. Meanwhile, the land carrying capacity during this same period was found to be declining at a rate of 6% per year, based on the population increase each year within a permanent land area.
