Although the individual factors have been well studied, their aggregated effect on size-selective erosional processes is highly uncertain. Therefore, this study concentrates on the aggregate size distribution and effective particle size distribution (PSD) of the aggregates in the soil loss, collected from different simulated hillslope positions and surface conditions. These simulated hillslope positions combine moisture content from the extremely dry to the saturated with related slope positions of 2, 5, and 12% steepness and different surface roughness (tilled and crusted surfaces) modelled in a laboratory rainfall simulator. Using hierarchical cluster analysis, the PSD of the aggregates was separated into three groups based on the differences in the 59–116 µm range of the PSD histograms, namely, macro-aggregates, 50–250 µm sized micro-aggregates, and <50 µm sized fractions were classified into distinct groups, although some micro-aggregate samples were classified into the macro-aggregate group. PSDs from the 50–250 µm aggregate size fraction were clustered into a group of macro-aggregates if the PSD changed with time (during the rainfall event), notably on rough surfaces. The role of the specified size range in the classification is believed to be due to the parallel presence of aggregates and single particles in this range. As aggregates have a lower density than mineral particles, they tend to be enriched in soil loss under low-energy runoff conditions. Moreover, all samples in the <50 µm fraction clustered into the macro-aggregate group were eroded from the smooth/crusted surface, probably due to the presence of larger particles. The results indicate that the combined effect of erosional factors is not apparent, and the impact of the crust and extreme moisture content on the selectivity and size distribution of the sediment requires further investigation.

The maturation phase of main varieties within the Carpathian Basin falls in a period of extremely high temperature - reaching, or even exceeding, 35-40 °C - and atmospheric drought. This detains the desirable fruit growth. In order to restore or even save the domestic raspberry production and market, introduction of greenhouse or polytunnel solutions is needed. Experimental plantations of three different raspberry varieties were set in two repetitions: covered and uncovered versions. Each cover has characteristic light reflection /absorption/ transmission which should generate devious environmental conditions and also different plant growth. Besides the monitoring of elementary biological indicators a wide range of sensors (temperature, humidity, solar irradiation, spectroradiometer) were used to quantify the difference between cover materials to find the optimal tunnel material for maximal plant productivity. © INMA Bucharest / Romania. Одним з найбільших викликів виробництва малини в Угорщині сьогодні є зменшення несприятливого впливу змін клімату. Фаза дозрівання основних сортів в межах Карпатського басейну потрапляє в період надзвичайно високих температур та посухи - досягає, або навіть перевищує 35-40°С. Це затримує бажаний ріст плодів. Для того, щоб відновити або навіть зберегти виробництво малини, необхідно впроваджувати парникові або політунельні рішення, щодо її вирощування. Експериментальні плантації трьох різних сортів малини були встановлені в двох повторах: покриті і відкриті способи вирощування. Кожне покриття мало характерне відбиття /поглинання/ світла, яке повинне генерувати умови навколишнього середовища, а також різне зростання рослин. Крім моніторингу елементарних біологічних показників для кількісного визначення різниці між покривними матеріалами для пошуку оптимального тунельного матеріалу для максимальної продуктивності рослин використовувався широкий спектр датчиків (температура, вологість, сонячне опромінення, спектрорадіометр).
