Ultisol merupakan bagian terluas dari lahan kering yang ada di Indonesia yaitu sekitar 25% dari total daratan Indonesia. Tanah yang mempunyai kesuburan rendah karena bereaksi masam, kandungan bahan organik rendah, kadar hara P rendah dan kelarutan Al yang tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian beberapa bahan organik dan lamanya inkubasi terhadap peningkatan pH, P-tersedia, kapasitas tukar kation (KTK), penurunan Al-dd dan kejenuhan Al pada tanah Ultisol yang dilaksanakan di Laboratorium Fisika Tanah, Fakultas Pertanian, Universitas Sumatera Utara dan Laboratorium Socfin Indonesia, Medan. Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial dengan 2 faktor dan 3 ulangan. Faktor pertama adalah bahan organik terdiri dari kontrol (B0), kompos Tithonia diversifolia (paitan) (B1), kompos kulit durian (B2), kompos TKKS (B3), pupuk kandang ayam (B4), kompos paitan + pukan ayam (B5), kompos kulit durian + pukan ayam (B6), kompos TKKS + pukan ayam (B7). Faktor kedua adalah lama inkubasi terdiri dari inkubasi satu minggu (I1), inkubasi dua minggu (I2). Hasil penelitian ini menunjukkan bahwa pemberian bahan organik nyata meningkatkan pH, P-tersedia, KTK serta menurunkan Al-dd dan kejenuhan Al. Lama inkubasi nyata menurunkan pH tetapi tidak mempengaruhi P-tersedia, KTK, menurunkan Al-dd dan kejenuhan Al, serta interaksi bahan oganik dengan lamanya inkubasi nyata menurunkan Al-dd tanah tetapi tidak mempengaruhi pH, P-tersedia, KTK, dan menurunkan kejenuhan Al. Ultisol is the widest part of dry land in Indonesia, which is around 25% of the total land area of Indonesia. This soil type has low fertility due to the acid reaction, low organic matter content, low P nutrient content and high Al solubility. This study aims to determine the effect of giving some organic matter and the length of incubation on increasing pH, available P, cation exchange capacity (CEC), decreasing Al-dd and saturation of Al on Ultisol soil carried out at the Soil Physics Laboratory, Faculty of Agriculture, University of Sumatra North and Indonesian Socfin Laboratory, Medan. This study used Factorial Completely Randomized Design with 2 factors and 3 replications. The first factor was organic material consisting of control (B0), Tithonia diversifolia (paitan) (B1) compost, durian skin compost (B2), OPEFB compost (B3), chicken manure (B4), paitan + chicken compost (B5) , durian + pukan chicken skin compost (B6), TKKS + chicken compost (B7) compost. The second factor is the incubation period consisting of one-week incubation (I1), two weeks incubation (I2). The results of this study indicate that the addition of organic matter significantly increases pH, available P, CEC and decreases Al-dd and saturation Al. Duration of incubation markedly reduced pH but did not affect P-available, CEC, decreased Al-dd and Al saturation, and interaction of organic matter with marked incubation duration significantly reduced soil Al-dd but did not affect pH, available P, CEC, and decreased Al saturation.

Abstract In this study, the yield and nutrient content of wheat (Triticum aestivum L.) grown in greenhouse conditions and soil microbiological properties were investigated. Inoculating Amycolatopsis strains, including A.magusensis DSM 45510T, A.orientalis DSM 40040T, and A.azurea DSM 43854T was considered. The mixture of wheat straw (WS) was used to increase soil organic matter content by 5%. It was determined that the grain and straw yield of wheat increased significantly (P < 0.001) in inoculation with Amycolatopsis strains in soils without WS. However, inoculation with Amycolatopsis strains in soil with WS significantly decreased grain and straw of wheat yield. Also, it was found that soil microbial biomass and soil basal respiration (SBR) increased in inoculation with Amycolatopsis strains in both soils with and without WS. While it was established that Cmic:Corg ratio of the control group in the soil samples at the end of the harvest was 1.23, infusing with Amycolatopsis strains was observed to be around 2.95–3.31. Moreover, inoculation with Amycolatopsis strains in soils with WS varied between 0.32–0.40. In the same way, it was determined the microbial metabolic quotient (qCO2) was 2.58 in the control group. This meaning was between 5.67–5.82 in infusing with Amycolatopsis strains and 6.04–6.41 in inoculating with Amycolatopsis strains in soils mixed with ground wheat stalk. As a result, it suggested that the yield of wheat could be increased inoculation with A.magusensis, A.orientalis, and A.azurea, from Amycolatopsis strains, in soils with low soil organic matter content and soils that cannot be shown an increment in terms of organic matter content.

<p>Mediante el seguimiento de cultivos experimentales en suelos ácidos de los Llanos Orientales, durante un periodo de cinco años consecutivos (1997-2001), se evaluaron las poblaciones nativas de hongos micorrícicos arbusculares (MA) asociados con dos variedades de maíz: ICA- Sikuani V-110 y la variedad regional criolla Clavito, analizando su comportamiento bajo distintos tratamientos con abono orgánico (gallinaza), abono verde (Caupí) y testigo sin aplicación de materiales orgánicos, para un total de seis tratamientos. De 7.924 esporas analizadas se aislaron veinticuatro morfotipos identificados morfológica y molecularmente. Se determinó la relación de las condiciones del suelo (pH, los contenidos de materia orgánica, P, K, Al+++ y % saturación Al) con el comportamiento de las poblaciones de MA. Con la aplicación del Análisis de Regresión Múltiple (Stepwise), se obtuvieron coeficientes significativos (P≤ 0.001 y R2 ≥ 83) para todas las variables y se seleccionaron como variables predictivas principales el pH y la materia orgánica del suelo, que presentaron coeficientes significativos para cinco y cuatro de los siete modelos establecidos, respectivamente. La técnica molecular empleada basada en la Reacción en Cadena de la Polimerasa (PCR), con el uso de primers específicos, permitió la identificación confirmatoria de las esporas aisladas de los géneros <em>Glomus, Entrophospora </em>y <em>Gigaspora</em>. Además, mediante el uso de esta metodología se logró identificar la presencia del género <em>Glomus</em>en raíces de maíz altamente colonizadas.</p><p> </p><p><strong>Mycorrhiza populations analysis in corn (<em>Zea mays</em>) cultivated in acid soils under different agronomic treatments</strong></p><p>A study was carried out to evaluate the populations of native arbuscular mycorrhizas (AM) fungi on established crops on acid soils of the Colombian Eastern Plains, for a period of five years (1997-2001). Fungi spores were isolated from the crop-fungi association of two maize cultivars: ICASikuani V-110 and the regional cultivar Clavito. The mycorrhizal behavior was evaluated under six different organic fertilization treatments, which included green manure (cowpea), chicken manure and a control treatment (no application). From a total of 7924 spores, 24 different types of mycorrhiza were characterized using morphological and molecular analysis. The relation between soil conditions (pH, organic matter contents, P, K, Al+++ and % Al saturation) and AM fungi populations was analysed using a Stepwise Multiple Regression model. According to the regression coefficients obtained (P≤ 0.001 y R2 ≥ 0.83), soil pH and organic matter content were the independent variables that explained most of the variation observed in AM populations. The molecular methodology was based on the Polymerase Chain Reaction (PCR) and the use of specific primers allowed to identify spores from <em>Glomus</em>, <em>Entrophospora </em>and <em>Gigaspora</em>. This methodology also provided the identification of fungi from the <em>Glomus </em>genera in highly colonized maize roots.</p>

Resistance To Penetration

Acadia or dykeland soils have produced forages successfully for centuries. The formation of barren areas within very productive forage stands has been noted recently in some land-formed fields, indicating either poor germination or poor growing conditions. A survey was undertaken in 1988 to determine the differences in soil attributes between barren and productive areas, namely: topographical position, resistance to penetration, bulk density, pH, plant-available P2O5, -K2O, Ca, and Mg, salt content (as measured by conductivity and sodium adsorption ratio), and exchangeable and soluble Ca, Mg, K and Na. Barren areas had greater: plant-available P2O5, resistance to penetration (the differential ranged from 480 to 1440 kPa), bulk density (in the top 15 cm), salt and sodium content than the productive ones. The exchangeable and soluble Na:Mg and Na:Ca ratios were higher on barren areas than on productive areas. Organic matter content was lower on barren than on productive areas. Values for topographic position, pH, particle size classes and plant-available K2O, Ca, and Mg were similar between the productivity areas. The results of this survey indicate that the formation of barren areas appears to be mainly due to accumulation of excess salts, especially sodium. Reasons for salt accumulation in these areas are discussed. Key words: Acadia soils, dykeland, salt, sodium, organic matter, resistance to penetration

Experimental fires were performed during the summer-drought period in a Mediterranean maquis in the Castel Volturno Nature Reserve in south-western Italy. The two different fuel loads applied (4 kg m−2 and 2 kg m−2) resulted in complete and partial combustion of the vegetation, respectively. Soil organic matter content (SOM), total and available element concentrations (K, Mg, Na, Mn, Fe, Cu, Pb, Cd), microbial carbon, respiration, metabolic quotient (qCO2), and the coefficient of endogenous mineralization (CEM) were measured at intervals in the dry and wet seasons over a period of about 3 years, in burned and adjacent unburned soils. Soil samples (0–5 cm depth) were collected under the cover of Phillyrea angustifolia L., a dominant species in the study area. Both fires induced long-lasting increases in SOM. As indicated by the increase in CEM, part of the accumulated SOM was mineralized in the first 3 months after fire whereas part of the accumulated SOM was instead stable. Both fires increased the total and available fractions of nutrients and trace elements. During the first 3 months after fire, microbial biomass and qCO2 were higher in the burned soils, which were richer in nutrients, but were characterized by harsher environmental conditions compared to unburned soils.

Effect On Yield

During two consecutive years, chicken manure effects on yield and foliar nutrient content of tanier, and on chemical properties of the soil were evaluated. Treatments were 0, 25 and 50 t/ha of chicken manure incorporated into the soil prior to planting the first year. No significant differences in yield were found among the chicken manure treatments. This lack of differences was attributed to the high coefficient of variation found in the experiment. Nevertheless, with the application of 25 t/ha we observed a 17% and 122% increase in yield on the first and second year of the experiment, respectively, compared to yield in the check treatment. This increase in yield could be related to the ample benefit of applied organic matter, especially in low fertility soil. Only foliar nitrogen content showed a significant increase with the chicken manure application in both years, whereas potassium content increased with manure application during the second year. The application of chicken manure caused an increase of organic matter, electric conductivity and N, P, K and Mg content in the soil during the first year.

&lt;p&gt;The aim of this study was to evaluate the effects of long-term application of exogenous organic matter on soil organic matter and water storage. Addition of organic matter is of importance in sandy soils that are in general poor in organic matter, acidic, conducive to drought and used in agricultural production throughout the world. In this study the sandy podzol (63-74% sand) was amended with chicken manure or waste spent mushroom substrate through more than 20 years. Soil organic matter content, water retention curves, acidity and structural stability were determined at three depths in the top 60 cm in organic amended and control plots. Enrichment of the soil with chicken manure and spent mushroom substrate caused increase in soil organic matter content in the top 0-20 cm from 1.34 to 3.50% and from 0.86 to 4.71%, respectively. Corresponding increases in field water capacity were from 13.6 to 31.8 m&lt;sup&gt;3&lt;/sup&gt; m&lt;sup&gt;&amp;#8722;3&lt;/sup&gt; and from 17.7 to 27.2 m&lt;sup&gt;3&lt;/sup&gt; m&lt;sup&gt;&amp;#8722;3&lt;/sup&gt;. Both amendments improved soil structure, reaction and nutrient status. In general, these positive effects were greater in chicken manure than spent mushroom substrate amended soil and less pronounced at depths 20-40 cm and 40-60 cm compared to upper soil. Increase in the field water capacity and water storage capacity made the soils amended with&amp;#160; organic matter more drought resistant. Our findings provide valuable insights the spent mushroom substrate left after growing the mushrooms and chicken manure are environmentally friendly and economical viable soil management practices to increase soil quality and crop productivity.&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;&lt;p&gt;&amp;#160;Acknowledgements&lt;/p&gt;&lt;p&gt;The work was partially funded by the HORIZON 2020, European Commission, Programme: H2020-SFS-4-2014: Soil quality and function, project No. 635750, Interactive Soil Quality Assessment in Europe and China for Agricultural Productivity and Environmental Resilience (iSQAPER, 2015&amp;#8211;2020).&lt;/p&gt;

To ascertain the agronomic value of the material resulting from the compost-bedded pack (CBP) in dairy barns, a cross-over experiment was designed with eight dry non-pregnant Holstein cows. The study was performed in two 11-week periods. Bedding materials used were: (1) CBP with sawdust (S) and (2) CBP with forest biomass (FB). Samples were taken from the raw bedding materials and from the CBP across the experiment. We conducted an additional study preparing two piles, one of each CBP material, to accomplish a composting process of 3 months, where samples were also taken. Granulometry and some chemical composition characteristics of FB made it a suitable bedding material to be used as CBP, but its high moisture content limited the ability to absorb liquid manure. Both the degree of stability of the organic matter and the temperature evolution of CBP suggest that a real composting process did not occur. Finally, the composting process of the piles did not lead to any relevant change in CBP materials. From the agronomic point of view, S and FB present potentially valuable characteristics as regards organic amendment in the soil, thanks to their high organic matter content and low nutrient content.

Highly Weathered Soils

Plantains are produced in the mountainous region of Puerto Rico and are grown in highly weathered soils of low fertility and high degradation potential. Alternatives to mitigate soil degradation include the application of chicken manure and the placement of deleafed sigatoka-infected leaves on top of the soil (deleafing). The objective of this study was to determine the effect of chicken manure and deleafing on soil properties and plantain productivity. The experiment was conducted in a Dagüey soil series at the Agricultural Experiment Substation in Corozal, Puerto Rico. The treatments were: 1) 25 ton/ha chicken manure; 2) deleafing; 3) chicken manure + deleafing; and 4) control. Chicken manure was applied before planting, and leaves from deleafing were placed on the soil only in deleafing treatments. The application of chicken manure significantly increased soil aggregate stability, soil available phosphorous and nitrates. Also, plant growth and plantain yield increased with manure applications, and the days to flowering and harvest were reduced. There were no effects neither on soil bulk density, hydraulic conductivity nor on organic matter content. No significant difference in runoff volume was observed, but sediment load in runoff decreased. The deleafed leaves decreased soil penetration resistance.

Sawdust, straw, compost and manure were applied under dryland conditions to strawberry plantings at two locations. The effects on yield, leaf nutrient content, soil moisture, soil acidity and soil organic matter content were evaluated. Sawdust mulch and sawdust incorporation, the former being slightly better, produced highly significant increased yields over the check treatment and were superior to all other treatments. Soil moisture measurements showed that the sawdust treatments conserved soil moisture and this was regarded as the chief reason for the increased yields. The nitrogen, phosphorus, potassium, calcium and magnesium contents of leaves were affected somewhat by the treatments but the levels were considered adequate in all cases.Soil acidity was significantly increased in the sawdust plots but this was attributed to the additional nitrogen applied rather than to the sawdust per se. Sawdust incorporation, manure and compost treatments significantly increased soil organic matter content when compared to the check treatment.
