In this study, data from the satellite sensors TanDEM-X and Sentinel-2 were combined with national field inventory to predict forest above-ground biomass (AGB) stem volume (VOL) over a large area in Sweden. The sources evaluated both separately combination. study covers approximately 20,000,000 ha corresponds about 70% of Swedish area. was divided into tiles 2.5 × km2, which processed sequentia...

This study conducted during the season 2017 at ED-Duem Locality which is laid Northern White Nile State of Sudan, main objectives this was measurement, listing all acacia raddiana tree sites their assessed physical characteristics height, diameter breast height and were account abundance, dominance, survival % natural regeneration as species. The researcher used systematic circular sam...

Five weekly applications of Beauveria bassiana (Balsamo) Vuillemin, a genetically engineered isolate of Bacillus thuringiensis Berliner (Raven), and aldicarb (Temik) were compared for control of Colorado potato beetle, Leptinotarsa decemlineata (Say) in an irrigated desert cropping system. B. thuringiensis was applied using low and high label rates (1.17 and 7.0 l ha−1). B. bassiana was applied...

Forest dynamics were studied from 1993 to 1997 for individuals > 10 cm DBH in nine 1 ha permanent sample plots. They were established in natural flood plain forests located on the lower Ucayali river in the Peruvian Amazon. After inventories of three plots in each of three forest types, a light and a heavy felling treatment were applied to each of the two plots, while a third plot was kept untr...

This study investigated the potential of fusing low laser-sampling density LiDAR data with QuickBird panchromatic imagery for estimating stand volumes. The study area was in closed-canopy, mountainous Japanese cedar (Cryptomeria japonica) plantations in Japan. Stand volume in the area ranged from 250.5 to 913.1 m/ha and terrain was undulating with an elevation ranging from 135 to 391 m above se...

A practical two-stage procedure for determination of stand parameters of entire forest stands by means of fi eld plots and airborne laser scanner data has been developed and tested. In the fi rst stage, geo-referenced fi eld sample plots are related to the corresponding laser data, and relationships (regressions) between fi eld data and various canopy height and canopy density metrics that can ...

Point pattern analysis of forest inventory stem-maps may aid interpretation and inventory estimation of forest attributes. To evaluate the techniques and benefits of conducting point pattern analysis of forest inventory stem-maps, Ripley’s K(t) was calculated for simulated tree spatial distributions and for over 600 USDA Forest Service Forest Inventory and Analysis (FIA) plots in Minnesota and ...

Present investigations were carried out during 1998-2000 at Shivri farm of Uttar Pradesh Bhumi Sudhar Nigam, Lucknow, India, to study the effect of vermicompost application in reclaimed sodic soils on the productivity of potato (Solanum tuberosum), spinach (Spinacia oleracea) and turnip (Brassica campestris). The soil quality was monitored during the experiment followed by productivity. The tre...

The performance of canola (Brassica napus L.) was evaluated using various nitrogen levels and shoots cutting at New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during Rabi 2012-13. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement having four replications each. Nitrogen levels @ 0, 50, 75 and 100 kg ha were allotted to...

Four levels of vegetative competition wete used to quantify the growth of loblolly and shot-deaf pines (Pinus taeda L. and /? echinatu Mill.) in naturally regenerated, even-aged stands on the Upper Coastal Plain of southeastern Arkansas, USA. Treatments included: (I) no competition control, (2) woody competition control, (3) herbaceous competition control. and (4) total control of nonpine veget...
