The recent widespread increase in iron chlorosis on acid, sandy soils in Florida has led to studies of the underlying causes. The leaves on affected trees are deficient in iron (10). Field observations show that tree condition can be substantially improved by liming. Additions of iron sulphate to the soil has not improved tree condition noticeably. Recently foliage condition improved when small...

Managing tree health in urban environments is complicated due to the disconnect that exists between novel environmental conditions created by urbanization and those under which species evolved. Soils influence growth, but optimal nutrient pH recommendations are often informed agricultural horticultural norms do not typically include for forest species. At Arnold Arboretum Boston, Massachusetts,...

Tree species-mixing has been suggested as one option to counteract the adverse effects of global change on tree mineral nutrition, yet effect mixing nutrient availability remains poorly documented. We therefore analyzed current foliar (N, P, K, Ca, Mg) quantities and ilr balances (isometric log transformed ratios between elements or groups elements) for 261 European beech 248 Scots pine trees f...

Understanding site fertility constraints has lifted productivity of eucalypt plantations in East and South-east Asia through targeted application of inorganic fertilisers. Whilst most attention has been given to the supply of nitrogen and phosphorus in silvicultural prescriptions, and inoculation with mycorrhizal fungi is being undertaken by some companies, more attention is required to diagnos...

An experimental study was done in an attempt to utilize the benefits and uses of Moringa oleifera gum powder enhance nutritive value products developed by incorporating it orange (grape variety) watermelon juices. The yield percentage from tree (once) calculated. gums were collected tree, processed used for further purposes. determined its physic-chemical properties. watersoaked incorporated di...

Legume cover crops have various important effects on nutrient cycling in tropical fruit tree production: they (i) fix atmospheric N2 and may amend the soil and trees with N, (ii) recycle nutrients, and (iii) affect soil nutrient availability. Aboveground N accumulation usually is very large in legume cover crops as seen from Pueraria phaseoloides being 8 to 14 times higher than in intercropped ...

background non-alcoholic fatty liver disease (nafld) is the most common form of liver disease in many parts of the world. objectives the aim of the present study was to identify the most important factors influencing nafld using a classification tree (ct) to predict the probability of nafld. patients and methods this cross-sectional study was conducted in kavar, a town in the south of fars prov...
