oh it s pretty clear with facing climate change we re likely to get more severe weather so it s even more important to the future that we keep our soils healthy and get info from even on goldmark s through to. historian although much of the soil we have on earth is vulnerable to erosion it has water or wind erosion erosion has been identified as a very serious threat to our soils convicted because of the cold war movement what i wonder. there are 40 absolute in all things the extent of erosion is increasing or is specially where all the nutrients are in the finest particles party or did their nettings. humus and nutrients disappear in the rain and the wind what has taken thousands of years to create is a rooted away in the blink of an eye what remains is soil that has lost its
the worst case scenario for soil would be that. producers and consumers don t realize that that s where the nutrients come from that sustain life all life all life began and ends with the soil. this is about the immediate future possibly just one generation away. when we live used up the very thin layer of topsoil that we have at our disposal. we have to do away with the notion that the soil the ecosystem and nature are there to be exploited rather than interacted with if we re to have any kind of future at all. without life no soil. and with no soil. if people don t speak about nature as i speak about over and it s not over just
that they re in the perfect condition to be absorbed by plants along with soil moisture but soon gave in markets. you know it s all about life and death because you need that that cycle and that s what the soil food web it. the plants in the soil need one another they ve developed and perfected a mutual balance during the course of evolution that has become a self-sufficient entity. if you look at how a healthy soil ecosystem functions it s all about photosynthesis how much sunlight can i capture. with living plants those living plants then through photosynthesis pumped carbon into the soil and as they do that that carbon then in the soil feeds all that soil life and allows that soil to produce much much more.
a marathon on sugar alone. soils are meant to be there forever that s why we can t fertilize them with sugar i think that your slower you ll get muscle. and right now we will put on you know 100 kilos of nitrogen and between 40 and 60 of those kilos go somewhere else in the environment they re not taken up by the crop. monoculture and chemical fertilizers constitute a threat to the soil becomes passive in the nutrients and up in oceans lakes and other waterways. dangerous compounds in phosphorus based proto lizards become part of the food we eat. here we re going to force for us to get one problem with phosphorus fancy lies as is that they often contain cadmium. removing it is costly course. keeping it means lots of cadmium in our food in the future many problems
compaction is an increasing problem become more and more specialized which calls for more rationalize ation measures the machinery gets larger and heavier cultivation seasons become longer so we tell the land one it s went like these factors all costs oil compaction yield gradually decrease he says the soil is deprived of and to breathe or. this impacts the layers below ploughing depth which become almost like cement. it creates a kind of lid that won t let through any rainfall and that results in flooding it also prevents water from being filtered and groundwater reserves from being replenished. industrial monocultural food production creates problems. we ve promoted monoculture in
