BiZnomics- Why hydeoponics-1

Hydroponics is a system of soilless cultivation using water-based nutrients.

Hydroponics, by definition, is a method of growing plants in a water-based, nutrient-rich solution. Hydroponics does not use soil, instead, the root system is supported using an inert medium such as perlite, rock -wool, clay pellets, peat moss or vermiculite.

The hydroponic system offers farmers the ability to grow crops in areas where traditionally it would simply not be possible (like mountain lettuce at sea level in Sri Lanka). Growing hydroponically (as with vertical farming, aquaponics, aeroponics etc) also saves a lot of land space.

Many growers believe that growing in a soilless medium requires about the same effort as growing in soil. Not as fast as full Hydro-Growing in a soilless medium will get faster growth rates in soil, but cannabis plants will not grow as fast as a hydroponic medium that is able to get more oxygen to the roots.

Well managed hydroponic set-ups are also highly energy-efficient and their existence places less strain on the environment than many traditional ‘monoculture’ farming systems. Water is recycled throughout the hydroponic system, greatly reducing the overall volumes required. As a general benchmark, it is considered that the hydroponic system use as little as 10% of the water required for soil-based agriculture.

The Big Question Is Are You in the Right Job? 0 665

By : Chantal D

No matter what your job is, keep adding skills, expanding knowledge and building confidence.

Have you ever asked yourself if you are in the right job?

How about if, and when you should quit a job? You need to know when it’s simply time to double-down or move on from a position.

The first thing you need to do is a self-assessment. You need to ask yourself the right questions. You need to determine if the problem is the job itself, or you. Make the effort to take a serious look at if it’s you or the job. This assessment will focus your energy on fixing the right thing. Either the job or your approach and attitude about it.

If it is your attitude and approach, and there are benefits to the job, commit and anchor in. If you think the role is wrong, look at where you want to be, what other people are doing, where people are making money. Make a concentrated effort to move to the position that you want and the one that will serve you best.

When accessing your current role or a new one, review these points:

01. Company Performance and Culture

Company Performance and Culture

-Are the environment and people positive and supportive?  Or are people negative and tight with resources?

-Is the company ethical?

-Do people enjoy their jobs?

-Are people showing up on time?

-Do co-workers like each other?

-Do people feel secure in their positions?

 

2. Senior Management and Leadership

Senior Management and Leadership

-Do you like the mission?

-Does your boss respect you and your efforts?

-Are there clear goals on how to grow the business?

-Is company management investing in the business?

-Is the company forward thinking or reactionary?

-Does Senior Management appear smart, ethical and competent?

 

3. Compensation

Compensation

-Are you making money?

-Are you being fairly paid and your job title reflects the scope of your
responsibilities and what you actually do?

-Do people feel underpaid and overworked?

 

Opportunity

Opportunity

-If you aren’t making enough money are you learning other skills, making contacts, networking?

-What other benefits are you receiving that compensate for the poor pay?

-Do you know what you’re learning at work? Can you see your resume growing and feel your confidence increasing over time?

You might discover that a small, solvent company with a great leader might be the best option for you. But it starts with you, if your attitude is wrong, you will pass on good opportunities. Keep in mind, the position has to serve you and your best interests. Put yourself first. You have to be selfish until you can be generous. Once you decide that it’s in your best interest to move to a new position, keep these pointers in mind:

  1. The Big Question Is ArDecide that you are going to get a job and eliminate all other options
  2. Take the attitude that getting a job is your job
  3. Stay connected in the workforce
  4. Have the attitude that you will find a job
  5. Companies don’t hire resumes they hire people that can help move the company forward
  6. Do NOT rely on headhunters and recruiters to get you your next job
  7. Do NOT rely on the HR department and do everything to bypass them
  8. You in the Right Job?

As you look for a job, don’t just focus on one industry. Keep an open mind and focus instead on people. What kind of person would you want to work for? Who is doing the kinds of things you want to assist with? How much could you help them? Brainstorm three, four or five people today who could change your life forever.

No matter what your job is, you can always improve your situation in life. Keep adding skills, knowledge and confidence and you will become more valuable to the marketplace.

Nanotechnology in Agriculture System 0 504

Agriculture is the backbone of most of the developing countries in which a major part of their income comes from agriculture sector and more than half of their population depends on it for their livelihood.  The current global population is nearly 7.7 billion with 50% living in Asia. A large proportion of those livings in developing countries face daily food shortages as a result of environmental impacts or political instability, while in the developed world there is a food surplus. For developing countries, the drive is to develop drought and pest-resistant crops which also maximize yield. In developed countries, the food industry is driven by consumer demand which is currently for the fresher and healthier food products.

Specifically in agriculture, technical innovation is of importance with regard to addressing global challenges such s population growth, climate change and the limited availability of important plant nutrients such as phosphorus and potassium.

Nanotechnology has gained intense attention in the recent years due to its wide applications in several areas like medicine, medical drugs, catalysis, energy and materials. Those nanoparticles with small size to the large surface area (1-100nm) have several potential functions. These days, sustainable agriculture is needed. The development of nonchemical has appeared as promising agents for the plant growth, fertilizers and pesticides. In recent years, the use of Nano materials’ has been considered as the alternative solution to control pant pests including insects, fungi and weeds.

Despite these potential advantages, the agricultural sector is still comparably marginal and has not yet made it to the market to any larger extent in comparison with other sectors of nanotechnology application.

Nanotechnology helps agricultural sciences and reduce environmental pollution of pesticides and chemical fertilizers by using the nano particles and nano capsules with the ability control or delayed delivery, absorption and more effective and environmentally friendly and production of nano -crystals  to increase the efficiency of pesticides for application of pesticides with lower dose.

In the agricultural sector, nanotech research and development is likely to facilitate and frame the next stage of development of genetically modified crops, animal products inputs, chemical pesticides and precision farming techniques. The use of nanotechnology in agriculture has been mostly theoretical but it has begun and will continue to have a significant effect in the main areas of the food industry development of new functional materials, product development and design of methods and instrumentation for food safety and bio-security.
