Measure Land Moisture by Satellite

No longer will Australian farmers waste their time working land that has no future. Satellite technology has improved to the point where moisture level of farmland can be determined. Waiting for rain that will make no difference is info that farmers can now 'bank' on.

Measuring moisture level is now something done by computer, from aerial surveys. The labor-intensive, time-consuming chore is a thing of the past. Soil that has potential rejuvenation can be targetted. The cost is out of the reach of individual farmers at present but the price is falling.

It is possible, if use of the new technology becomes widespread, that the output of certain crops can be estimated. Potential shortages will be foreseen and action taken in future plantings. When weather predictions are included the position of markets months ahead will be known.

Another Use for Fish Sperm

Pollution is a big problem, particularly from industry which pumps unwanted metals into the soil just about everywhere in the world. Getting rid of this had been an issue looking for a solution for decades. The answer could be at hand from a very weird source.

Fish sperm has a property making it ideal for the purpose. It literally hoovers up the metal particles. The sperm contains high amounts of DNA. This contains phosphate which strongly attracts metals. The metal/phosphate compound can be taken out with neodymium magnets consisting of trivalent iron, dysprosium and neodymium.

In Italy herring sperm was first identified as being useful in cleaning up the environment. With salmon being bred commercially, it is seen as a better source of fish sperm. The substance has been thrown away as waste until now.

New iHerd App Helps Australian Farmers

If labor costs are high in a country it is necessary to turn to technology to efficiently do the job. Australian farmers have been world leaders in applying technology to tasks. Thus, there is an increasing demand for skilled labor on farms. This obviously goes against tradition.

A new app for farmers has been released called iHerd. The app keeps an eye on cattle as they move around. Tracking is much easier. Gathering of cattle into yards is reduced. Cattle have monitoring tabs fitted to them. As they come in to drink, tags are identified and weight is taken. Animals of a certain weight can then be selected out.

An important benefit is that the knowledge has improved production of healthy cattle. Of course, farmers themselves have to learn new skills. This they are doing very well indeed. New technology is being adopted and applied rapidly.

A more technologically based farming sector could attract skilled young people back to the land. This is not a goal, though it could happen. They will have accept losing some of the benefits of city life and be more hardier in there nature.
