Yield Decline

Soil samples from paired 'old' and 'new' sugar cane soils from 6 contrasting sites in 3 climatically contrasting areas of North Queensland were analysed to identify changes in soil chemistry resulting from continuous sugar cane monoculture. The aim was to identify soil factors that may be associated with, or act as triggers to, the expression of sugar yield decline. It was found that there was no consistent effect of time under sugar monoculture on soil chemical properties across all sites, when either the distributions of properties through the soil profile, or property values at specific depths, were considered. However, marked effects were noted at some sites with respect to some soil properties, and the lack of consistent results across all sites may therefore be attributable to the inherent differences between the soils sampled. These effects were generally consistent with soil acidification.

The article assesses the effects of amphibolite applied to the planting holes of spruces on the soil chemistry. The sampling was conducted fourteen growth seasons after the establishment of the experimental spruce plantation. In both treatments (control and amphibolite) the soil samples were taken from the interior of the planting holes as well as from the intact area around the planting holes. Fourteen growth seasons after application the effects of the pulverised amphibolite were not marked despite being detectable. In comparison with the control the soil in the planting holes of the amphibolite treatment showed significantly higher soil reaction, concentration of available phosphorus and partially also concentration of exchangeable Ca. All the significant effects of amphibolite were confined to the soil inside the planting holes. As for the evaluated chemical properties no significant undesirable effects of the amphibolite on soil chemistry were recorded.

The Impact

This result aims to determine the impact of land fires on chemicals soil. Forest fire data Obtained in the region of Research and Edication Forest Bukit Soeharto Mulawarman University (HPPBS UNMUL). The method was used on research are descriptive and comparative by comparing the result of soil chemicals properties analysis of burn and unburned lands. The soil chemistry properties of this result is pH, Organic Carbon, Nitrogen, Phosphor and Potassium. Soil sampling was random system on this methods. Soil samples be distinguished by type and depth of soil sampling. The results of the soil analysis chemical properties then was compared based on assessment of soil chemical properties which refers to the assessment criteria soil chemical properties developed by Soil Research Institute Bogor, 2005. The results showed the fires occurring after 1 year influence of soil chemicals properties such as pH, Organic Carbon, Nitrogen, Phosphor and Potassium.

The aim of the study was to compare a long term effect of oppositional fertilization methods, organic vs. conventional, on chosen soil chemical properties. Soil samples were collected from organic farms with at least 10-years history of organic management and from neighboring conventional farms. In total soil samples from 66 farms distributed all over Poland were collected. The following properties were analyzed: organic carbon (Corg), total nitrogen (Ntot), pH, exchangeable forms of P, K and Mg. In general organic management resulted in slightly higher soil pH. Bigger differences were found in case of C and N content. Thanks to organic fertilization method in loamy and clay soils C content was higher by 13.5% and N content was higher by 20.3%. The same tendency, although not so marked, was found on sandy soils. Conventional fertilization resulted in higher content of exchangeable P, especially on sandy soils. Almost the same content of exchangeable K was found on both farm types. Higher amounts of exchangeable Mg was found on organic farms on each soil type: sandy, loamy and clay. In the same time bigger disproportions of Mg content were found on organic farms (30–112 mg Mg kg−1) than on conventional farms (30–87 mg Mg kg−1).

The lack of information concerning the variability of soil properties has been a major concern of researchers in the Amazon region. Thus, the aim of this study was to evaluate the spatial variability of soil chemical properties and determine minimal sampling density to characterize the variability of these properties in five environments located in the south of the State of Amazonas, Brazil. The five environments were archaeological dark earth (ADE), forest, pasture land, agroforestry operation, and sugarcane crop. Regular 70 × 70 m mesh grids were set up in these areas, with 64 sample points spaced at 10 m distance. Soil samples were collected at the 0.0-0.1 m depth. The chemical properties of pH in water, OM, P, K, Ca, Mg, H+Al, SB, CEC, and V were determined at these points. Data were analyzed by descriptive and geostatistical analyses. A large part of the data analyzed showed spatial dependence. Chemical properties were best fitted to the spherical model in almost all the environments evaluated, except for the sugarcane field with a better fit to the exponential model. ADE and sugarcane areas had greater heterogeneity of soil chemical properties, showing a greater range and higher sampling density; however, forest and agroforestry areas had less variability of chemical properties.

Abstrak. Pemberian kompos dan mikoriza merupakan salah satu alternatif untuk meningkatkan pertumbuhan bibit kakao dan dapat memperbaiki sifat kimia tanah.  Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri atas dua faktor ( kompos dan  jenis mikoriza) dengan pola 3 x 3 dan tiga kali ulangan. Hasil penelitian ini menunjukkan bahwa faktor tunggal kompos berpengaruh nyata terhadap N-total dan tinggi tanaman namun tidak nyata terhadap pH, C- organik, P- tersedia, Kdd, KTK, diameter batang dan luas daun. Perlakuan mikoriza secara tunggal  serta kombinasi antara kompos dan mikoriza tidak berpengaruh nyata terhadap sifat kimia tanah dan pertumbuhan tanaman. Perlakuan terbaik yaitu 30 g kompos dan 10 g jenis mikoriza Glomus sp + Giga spora. The Effect of  Compost and Mycorrhizal on Changes in  Soil Chemical Properties and Growth of Cocoa (Theobroma cacao L.)Abstract. Provision of compost and mycorrhizae is one alternative to increase the growth of cacao seedlings and can improve soil chemical properties. This study used a factorial Randomized Block Design (RBD) consisting of two factors (compost and mycorrhizal type) with a 3 x 3 pattern and three replications. The results of this study indicate that the single compost factor had a significant effect on total N and plant height but was not significant for pH, organic matter, P-available, Kdd, CEC, stem diameter and leaf area. Single mycorrhizal treatment and the combination of compost and mycorrhizae did not significantly affect soil chemistry and plant growth. The best treatments were 30 g of compost and 10 g of mycorrhizal Glomus sp + Giga spore
