Notable Increase

The dramatic growth of the world’s population is increasing the pressure on natural resources, particularly on soil systems. At the same time, inappropriate agricultural practices are causing widespread soil degradation. Improved management of soil resources and identification of the potential agricultural capability of soils is therefore needed to prevent further land degradation, particularly in dryland areas such as Egypt. Here, we present a case study in the El-Fayoum depression (Northern Egypt) to model and map soil suitability for 12 typical Mediterranean crops. Two management scenarios were analyzed: the current situation (CS) and an optimal scenario (OS) of soil variables. The Almagra model was applied to estimate soil suitability under CS and OS. Management options based on the CS assessment were proposed to reduce some limiting factors: a fixed value of 2 dSm−1 for soil salinity and 5% for sodium saturation; these defined the OS. Under optimal management, the OS scenario showed potential, where a notable increase of the area covered by a high suitability class (around 80%) for annual and semi-annual crops was observed. There was also a marked increase (about 70% for CS and 50% for OS) for perennial crops shifting from the marginal to moderate soil suitability class. The results reveal the importance of proper management to massively alter soil suitability into better states in order to achieve sustainable land use in this fertile agro-ecosystem.

Abstract Height, basal diameter, and crown width were determined for 2-to 16- year-old black walnut trees in 61 plantations distributed throughout Kentucky. Measurements from the 3050 trees sampled were used to develop height/age, diameter/age, and crown width/diameter equations and curves. These curves provide benchmarks for evaluating the early growth of typical plantations. Annual height and diameter growth were compared among different geologic substrates, landscape positions, levels of competition control, and soil suitability classes. At an average age of 6 years, height and diameter growth averaged 0.9 ft/yr and 0.2 in./yr, respectively, for all 61 plantations. Height growth was 35% greater for plantations located on suitable soils compared to plantations on soils of questionable suitability. Soil suitability did not affect diameter growth, but plantations with good competition control had 50% greater diameter growth compared to plantations with fair or poor competition control. Results of this study re-emphasize two principles of black walnut management: (1) only plant on good sites and (2) always control competition. North. J. Appl. For. 6(1):17-20, March 1989.

Groundwater recharge below ponded rice fields is a significant contributor to rising groundwater levels and the threat of soil and water salinisation. Reduced groundwater recharge is essential for sustainable rice based, irrigated farming systems in southern Australia. Currently a soil is deemed as suitable for rice production if 1 soil profile per 4 ha contains 2 m or more of continuous medium or heavy clay textured material. However, this study showed clay content to be a poor predictor of groundwater recharge. Electromagnetic induction surveys of rice fields can show variation in soil physico–chemical properties across rice fields. This allows the delineation of distinctly different areas of a field based on EM readings and allows accurate targeting of soil sampling and measurements. This study used soil chemical and physical properties and groundwater recharge data to assess the adequacy of the current rice soil suitability classification method. A 3-stage classification scheme of rice land suitability is proposed including EM31 soil mapping and measurement of soil sodicity as key components. The proposed scheme is as follows: (i) include the soil as suitable if the EM31v measurement is equal to or greater than 150 mS/m; (ii) if EM31v <150, include the soil if the ESP of the top 60 cm of the soil is greater than 6, or the ESP of the depth interval between 60 and 150 cm is greater than 12; (iii) all other soils are excluded from ricegrowing. The proposed scheme's ability to correctly identify low permeability soil in rice fields as suitable for rice growing was confirmed by the recharge values measured in these fields.
