As the use of forest harvesting residues for energy production gains popularity, debate continues regarding the long-term sustainability of whole tree harvesting (WTH). This practice removes nutrient-rich twigs that only account for a small fraction of harvest residues, emphasising the need to develop nutrient-efficient alternatives to WTH. This study assessed N, P, K, Ca, and Mg distributions ...

the objective of this study was to determine the allowed and desired limits for heavy soils of texture (clay loom), as it has operational capability (friability), these limits were 6.34 mm for planting and 10.62 mm for harvesting in each raining or irrigation episode. we determined some factors that affect soil wetness and water content as follow: the amount and severity of rain, the condition ...

In addition to transferring about 16 percent of GDP from exporters to importers, Uzbekistan’s quasi-fiscal multiple exchange rate regime generates identifiable welfare losses of 2–8 percent of GDP on import markets and up to 15 percent on export markets. These excess burdens have increased substantially with the growing difference among exchange rates. The welfare analysis allows some conclusio...

Two harvesting methods for utilization of understory biomass were tested against a conventional harvesting method to determine relative costs. The conventional harvesting method tested removed all pine 6 inches diameter at breast height (DBH) and larger and hardwood sawlogs as tree length logs. The two intensive harvesting methods were a one-pass and a two-pass method. In the one-pass method, a...

The sugarcane borer, Diatraea saccharalis (F.) (Lepidoptera: Crambidae), is the key insect pest of sugarcane, Saccharum spp., grown in Louisiana. For more than 40 years, Louisiana sugarcane farmers have used a value of 10% internodes bored at harvest as the economic injury level (EIL). Three plant-cane studies were conducted to re-evaluate the long-standing sugarcane borer EIL level using the m...

A study was conducted to investigate honeybee colonies absconding from beehives and its financial implication among beekeepers in Tabora and Katavi regions, Western Tanzania. Four districts were selected on the basis of adoption of improved beehives. A total of 198 beekeepers were randomly selected for interviews. Data collected from beekeepers using a questionnaire were supplemented with data ...

Abstract The subject of this study was to evaluate the visible crop losses during mechanized harvesting grapes, assess impacts changes in machine parameters and thus look for possibility reducing when utilizing method harvesting. A comparison with amount arising from manual also monitored. research results indicated average total 1.10–5.62% harvested monitoring revealed occurring area columns s...
