Dit was nou 'n baie lekker kuiertjie gewees. Ons het behoorlik gesels oor klomp lekker onderwerpe wat so in Toeka & NOU se naam pas. Baie dankie @CC Kriegler , @Heidie Kriegler , @Amadea Knoetze , @Dirk V zyl , @Marie Wessels , @Marinda Marx en @Jaco van Biljon al het die klank so nou en dan met Wi-Fi probleem gemaak en die video nie so lekker saam wou speel nie het ons gesels en gekuier vir sommer ver vir by tyd, is as of die tyd stil gaan staan het.

DIY Grond pH toets al wat jy benodig is Koeksoda en Asyn en 2 Glas bottels. Grondsuurheid of Alkaliniteit: Plaas 2 eetlepels grond in 'n Glas bottel en voeg ½ koppie asyn by. As die mengsel bruis, het jy alkaliese grond. Plaas 2 eetlepels grond in 'n bottel en maak dit nat met gedistilleerde water. Voeg ½ koppie koeksoda by. As die mengsel bruis, het jy suur grond. As dit nie op enige van die toetse reageer nie, het die grond 'n neutrale pH. 'n Baie hoë of baie lae grond pH kan lei tot 'n tekort aan plantvoedingstowwe of toksisiteit. 'n pH-waarde van 7 is neutraal; mikrobiese aktiwiteit is die grootste en plantwortels absorbeer/toegang voedingstowwe die beste wanneer die pH in die 5.5 tot 7 reeks is. Sodra jy jou grond pH vasgestel het, kan jy dit verander of aanpas. Suur (suur) grond word teenwerk deur fyn gemaalde kalksteen toe te dien, en alkaliese (soet) grond word behandel met gemaalde swael.

by Chinese Academy of Sciences Soil is often perceived simply as "dirt," but in reality, it is a dynamic, living system that acts as Earth's natural sponge. Unfortunately, common agricultural practices—including deep plowing and the use of heavy machinery—can severely disrupt this natural system, according to a new study led by Dr. Shi Qibin from the Institute of Geology and Geophysics of the Chinese Academy of Sciences, in collaboration with international partners. The study, published in Science, shows that healthy soil contains a natural internal "plumbing" network of microscopic pores and channels that allow water to infiltrate deeply into the ground, where it becomes available to plant roots. Frequent plowing or heavy tractor traffic not only disrupts soil structure but also reduces its ability to help crops withstand both flooding and drought. The team used a novel technique to observe subsurface soil processes without excavation. The researchers converted standard fiber-optic cables—similar to those used in high-speed internet networks—into a large-scale sensor array installed across an experimental farm at Harper Adams University in the United Kingdom. By using the array to detect tiny ground vibrations generated by water flow, the researchers were able to monitor water movement through the soil minute by minute. Using high-resolution fiber-optic data, they observed that rainfall tends to pool near the surface in heavily cultivated soil. Because water remains shallow, it evaporates rapidly in sunlight, leaving deeper soil layers dry.
