TL;DR: In the field of chemical weed control there is a constant demand for a reagent that will render the soil permanently sterile, for use on graveled driveways, parking areas, railroad right of ways, and similar areas where any plant growth is a nuisance as mentioned in this paper.
Abstract: does not appear. First page follows. Introduction In the field of chemical weed control there is a constant demand for a reagent that will render the soil permanently sterile, for use on graveled driveways, parking areas, railroad right of ways, and similar areas where any plant growth is a nuisance. Although arsenic has proved most effective (14)4 for this purpose, its use is always attended by a poison hazard. For this reason it seems desirable to find a soil sterilant that is nonpoisonous to man and animals. The known toxicity of boron compounds to plants suggests the possibility of their use for this purpose. While it is recognized that toxic concentrations of boron occur in soils in certain regions in California and Nevada (19), (23), (32) and that the leaching of additional boron compounds into the underground waters in these regions is undesirable, there are large areas in these states, and others, where such a condition does not exist. In fact, as the data presented in this paper will show, one of the most promising uses for boron compounds is in the control of range weeds in the north-coast counties of California where the underground waters are not utilized for irrigation. It seems therefore that such materials may find extensive use in many places. On the other hand, it is well to point out at the outset that wherever boron is present in toxic quantities in soils, and wherever crop plants may be affected, boron compounds should not be used in weed control.

TL;DR: In this paper, the Gottinger Akademie stellte the Frage: „Ob die sog unorganischen Elemente, welche in der Asche der Pflanze gefunden werden, auch dann in den pflanzen sich finden, wenn sie denselben von ausen nicht geboten.
Abstract: Genau vor einem Jahrhundert, im Jahre I838, stellte die Gottinger Akademie die Frage: „Ob die sog unorganischen Elemente, welche in der Asche der Pflanze gefunden werden, auch dann in den Pflanzen sich finden, wenn sie denselben von ausen nicht geboten werden“Die Beantwortung durch Wiegmann und Polstorff (1842) widerlegte nicht nur die schon durch die Fortschritte der Chemie uberholte Anschauung, das die „erdigen Bestandteile“der Pflanze in ihr selbst gebildet wurden (SchraDer 1800), sondern sie erbrachte daruber hinaus den Beweis — und das mit auch heute noch durchaus anzuerkennender Methode —, das die Aschenbestandteile nicht mehr oder weniger zufallige Verunreinigungen des Pflanzenkorpers darstellen, sondern als ganzes oder wenigstens zum Teil notwendig sind Damit war eine Fulle von Fragen aufgerollt, deren Beantwortung aber, trotz 100 Jahren intensivster und vielseitigster Forschung, in den meisten Punkten noch recht wenig befriedigt Das gilt vor allem fur die Frage nach der stoffwechselphysiologischen Bedeutung der als notwendig erkannten Aschenelemente, doch ist eine ganze Reihe weiterer Fragen der mineralischen Pflanzenernahrung uber den Zustand mehr oder weniger begrundeter Hypothesen noch nicht hinausgekemmen

TL;DR: In this article, Nagyhorcsok Kiserleti Telepen vizsgaltuk a K es B elemek kozotti kolcsonhatasokat 1988-ban napraforgo jelzőnovennyel.
Abstract: Meszlepedekes csernozjom valyogtalajon, az MTA TAKI Nagyhorcsok Kiserleti Telepen vizsgaltuk a K es B elemek kozotti kolcsonhatasokat 1988-ban napraforgo jelzőnovennyel. Az alaptragyazas 100–100 kg N es P2O5·ha-1 volt. A K-szinteket 0, 1000 es 2000 kg·ha-1 K2O feltoltő adaggal, a B-szinteket 0, 20, 40 es 60 kg·ha-1 adaggal allitottuk be 1987 őszen, lucerna elővetemeny utan. A műtragyakat Ca-ammonium-nitrat, szuperfoszfat, 60%-os KCl es 11%-os borax formaban alkalmaztuk. Főparcellakent a 3 K-szint, alparcellakent a 4 B-szint szolgalt. A kiserletet 12 kezelessel 3 ismetlesben, osszesen 36 parcellaval, osztott parcellas (split-plot) elrendezesben allitottuk be. A termőhely szantott retege 5% koruli CaCO3-ot, 3% humuszt, 20–22% agyagot tartalmazott. A talaj eredetileg N, Ca, Mg es Mn elemekkel jol, kaliummal kozepesen, P es Zn elemekkel viszonylag gyengen ellatottnak minősult. A talajviz 13–15 m melyen helyezkedik el, a termőhely aszalyerzekeny. A napraforgo tenyeszideje alatt 290 mm csapadekot kapott (a soke...

TL;DR: In this article, a 2-year study failed to show a significant yield response from soil applications of boron to eight-year-old muscadine grape vines; however, a definite trend toward yield response was evident from linear regression models.
Abstract: A 2‐year study failed to show a significant yield response from soil applications of boron to eight‐year‐old muscadine grape vines; however, a definite trend toward yield response was evident from linear regression models. No difference in B levels of tissue occurred the initial year but in the second year, the tissue from the highest B rate was significantly higher than other treatments. Boron content of the soil correlated well with B treatment levels (r = .88). Fruit soluble solids were not related to B treatments.
